Unhandled error Error: Data cannot be encoded in JSON error at firebase serverless functions

I'm trying to deploy an api for my application. Using these codes raises Unhandled error "Error: Data cannot be encoded in JSON.
const functions = require("firebase-functions");
const axios = require("axios");
exports.getDatas = functions.https.onCall(async (d)=>{
functions.logger.log(d["name"]);
cname = d["name"];
ts1=d["ts1"];
ts2=d["ts2"];
const data = await axios.get(
"https://api.coingecko.com/api/v3/coins/" +
cname +
"/market_chart/range?vs_currency=usd&from=" +
ts1 +
"&to=" +
ts2,
);
functions.logger.log(data);
return {data: data};

When this code invoked it logs data correctly but i can not return it at last. Anyone can help?

The problem appears to be that you're trying to return the entire Axios response. This cannot be serialised as JSON due to circular references.
Simply return the response data instead. You can also make your URL construction simpler (and safer) using the params option
exports.getDatas = functions.https.onCall(async ({ name, ts1, ts2 }) => {
functions.logger.log(name);
// 👇 note the destructure here
const { data } = await axios.get(
`https://api.coingecko.com/api/v3/coins/${encodeURIComponent(name)}/market_chart/range`,
{
params: {
vs_currency: "usd",
from: ts1,
to: ts2,
}
}
);
functions.logger.log(data);
return { data };
});

const showAlert = (msg) => {
let alertBox = document.querySelector('.alert-box');

alertMsg.innerHTML = msg;
alertBox.classList.add('show');
setTimeout(() => {
alertBox.classList.remove('show');
}, 3000);
}
with this i always get the same error, it doesn't save the users to the database, and its kinda irritating. i would like help for this type of error as soon as possible. this for a school project and time is coming short...

API getting multiple Calls

My program in a nutshell. If the trigger word is detected in the message, my application creates invoices.
The issue: Multiple calls to the trigger function. All of the requests to the API are simultaneous. This causes my data to have problems.
I have added the async and await to wait for the trigger function to complete. But it seems my calls are still being called all together.

Here's an example of the api being called. this is using graphql

export const deleteInvoice = async(id) => {

console.log(invoiceId, "THIS I S INVOICE DELET EDELETE DELETE DELTE ")
try {
const token = "zCtQa00zlorbFFum6I7Rlzc0QwMDoS";
const shema = `
mutation ($input: InvoiceDeleteInput !) {
invoiceDelete(input: $input) {

inputErrors {

}
}
}`;
//About to submit my shema to waveapps
const API_URL="https://gql.waveapps.com/graphql/public"
const bussID = "QnVzaW5lc3M6ZTIyZmVhODEtNjg5OC00N2ZiLTgzOGItYWMyYzllNDZiM2Jk";
let watch = await axios(API_URL, {
method: "POST",
headers: {
Authorization: token ? `Bearer ${token}` : "",
"Content-Type": "application/json",
},
data:{

}
},
},
})
console.log(watch.data)
} catch (error) {
console.log(error.response)
}
//console.log("return delete invoice complete")
};
I have used async/await and promises.
When multiple calls are made. The await and promises are still being called at the same time. Not sure what else to look at? any suggestions please. I have spent a week on this.

Return empty array in Fastify handler with async/await function

I'm trying to make a web3 wallet with Moralis with Fasitify in back and VueJS in front.
(I would like to say that I already do this in web client (vuejs) and everything works well!)
In my back, I fetch all the asset from user. It works, I get them all well and I can send them back to the front
But I need to process/sort the data to recover only part of it and send it to the front to avoid doing too much treatment at the front and reduce your workload.
I do that :
*handlers/token.js*
const getTokenBalances = async () => {
let userTokens;
const options = {
chain: "bsc",
address: "0x935A438C29bd810c9aBa2F3Df5144d2dF4F3c0A0",
};
userTokens = await Moralis.Web3API.account.getTokenBalances(options);
return userTokens;
};
and if I return userTokens, I had it in Postman. But now, I do something like :
const getTokenBalances = async (tokens) => {
let userTokens;
let userBalances = [];
const options = {
chain: "bsc",
address: "0x935A438C29bd810c9aBa2F3Df5144d2dF4F3c0A0",
};
userTokens = await Moralis.Web3API.account.getTokenBalances(options);
userTokens.forEach((token) => {
if (
!token.name.match(/^.*\.io/) &&
!token.name.match(/^.*\.IO/) &&
!token.name.match(/^.*\.net/) &&
!token.name.match(/^.*\.Net/) &&
!token.name.match(/^.*\.com/) &&
!token.name.match(/^.*\.org/)
) {
getTokenPair(token).then((value) => {
if (value > 2) {
checkTokenPrice(token).then((price) => {
if (price > 0.001) {
userBalances.push(token);
}
});
}
});
}
});
userBalances.sort((a, b) => {
return b.total_value_usd - a.total_value_usd;
});
return userBalances;
};
userBalances its always empty in my response in Postman (And I don't understand why ?)
The getTokenPair function :
const getTokenPair = async (token) => {
const BNBTokenAddress = "0xbb4CdB9CBd36B01bD1cBaEBF2De08d9173bc095c"; //BNB
const options = {
token0_address: token.token_address,
token1_address: BNBTokenAddress,
exchange: "pancakeswapv2",
chain: "bsc",
};
try {
const pairAddress = await Moralis.Web3API.defi.getPairAddress(options);
let amount = 0;
//console.log("token pairAddress : " + pairAddress.pairAddress);
if (pairAddress.token1.symbol === "BUSD") {
try {
let reserve = await getPairReserves(pairAddress.pairAddress);
amount += reserve / 10 ** 18;
} catch (err) {
console.log("error getReservesBUSD : " + err);
}
}
if (pairAddress.token1.symbol === "WBNB") {
try {
let reserve = await getPairReserves(pairAddress.pairAddress);
amount += reserve / 10 ** 18;
} catch (err) {
console.log("error getReservesWBNB : " + err);
}
}
//console.log("amount : " + amount)
return amount;
} catch (err) {
console.log("error getPair : " + err);
}
};
and the checkTokenPrice function :
const checkTokenPrice = async (token) => {
let price;
const options = {
address: token.token_address,
chain: "bsc",
exchange: "PancakeSwapv2",
};
try {
const priceToken = await Moralis.Web3API.token.getTokenPrice(options);
price = priceToken.usdPrice.toFixed(7);
token.price = priceToken.usdPrice.toFixed(7);
token.balance = insertDecimal(token.balance, token.decimals);
token.total_value_usd = (token.balance * token.price).toFixed(2);
return price;
} catch (err) {
console.log("error tokenPrice : " + err);
}
};
They are await method in all the function I use so maybe there is a connection.
Thanks for you help !
**** EDIT *****
I solve my problem like this :
const getTokenBalances = async () => {
let userTokens;
let userBalances = [];
const options = {
chain: "bsc",
address: "0x935A438C29bd810c9aBa2F3Df5144d2dF4F3c0A0",
};
userTokens = await Moralis.Web3API.account.getTokenBalances(options);
for (token of userTokens) {
if (
!token.name.match(/^.*\.io/) &&
!token.name.match(/^.*\.IO/) &&
!token.name.match(/^.*\.net/) &&
!token.name.match(/^.*\.Net/) &&
!token.name.match(/^.*\.com/) &&
!token.name.match(/^.*\.org/)
) {
let value = await getTokenPair(token);
if(value > 2) {
let price = await checkTokenPrice(token);
if (price > 0.001) {
userBalances.push(token);
}
}
}
}
return userBalances;
};
Thanks for the help ! ;)

AdonisJS - SyntaxError. Unexpected character ' '

I am trying to fetch all talent resource from the database but when I tried the endpoint on Postman, it returned a SyntaxError. Unexpected character '' error. I dont know where that character is coming from as postman hinted that the error is on Line 66 of my controller, but on checking the line 66 is an empty/blank line.
What could possibly cause this error?
My controller code (the method the API is calling is below)
async searchTalent({ request, response }) {
try {
const params = request.except('projectId');
let matchedTalents = [];
let talentIds = [];
const {tools, fullname} = params;
if(tools) {
const find = await Database.raw("SELECT * FROM pro WHERE MATCH tools AGAINST ('"+ tools +"' IN NATURAL LANGUAGE MODE)");
const talents = find[0];
if(talents) {
for(let t = 0; t < talents.length; t++) {
const talent = talents[t];
if(talent.active == true) {
const user = await User.query().where({id: talent.userId, active: true, type: 'talent', isDeleted: false}).first();
if(user) {
if(talentIds.length > 0) {
if(talentIds.includes(talent.id) === false) {
user.profile = talent;
talentIds.push(talent.id);
matchedTalents.push(user);
}
} else {
user.profile = talent;
talentIds.push(talent.id);
matchedTalents.push(user);
}
}
}
}
}
// for (let i = 0; i < tools.length; i++) {
// const tool = tools[i];
// }
} else if(fullname) {
const getUsers = await User.query().where('first_name', 'LIKE', '%%' + fullname + '%%').orWhere('last_name', 'LIKE', '%%' + fullname + '%%').where({ active: true}).orderBy('id', 'desc').get();
for (let i = 0; i < getUsers.length; i++) {
const user = getUsers[i];
if(user.type == 'talent')
{
const talent = await Pro.query().where({userId: user.id}).first();
if(talent)
{
user.profile = talent;
matchedTalents.push(user);
}
}
}
}
​
const data = matchedTalents;
​
return response.json({
data: data,
message: data.length + ' Talents fetched',
error: false
})
} catch (e) {
Event.fire('log::error', e.message)
return response.json({
data: [],
message: e.message,
error: true
})
}
}
I have tried searching and fixing since yesterday but all stackoverflow answers don't seem to address this issue.
