Hello,
I get this error whenever I call the netlify function. sometimes it works and sometimes not and I get this back
Request from ::ffff:127.0.0.1: GET /.netlify/functions/getS3URL?reqType=get
Response with status 200 in 2919 ms.

Angular:
api.service:
getS3URL(){
let queryParams = new HttpParams();
return this.http.get(`${baseUrl}getS3URL`,{ params: queryParams }).pipe();
}
in the component:
getS3URL() {
if (this.product.images[0]) {
this.api.getS3URL().subscribe({
next: (value: any) => { console.log('resp: ',value)}
, error: (err) => { console.log('error', err) }
})
}
}
Netlify function:
import dotenv from 'dotenv'
import aws from 'aws-sdk'
import crypto from 'crypto'
import { promisify } from "util"
import { Response } from '@netlify/functions/dist/function/response'
dotenv.config()
const randomBytes = promisify(crypto.randomBytes)
const region = "us-east-1"
const bucketName = "-----"
const accessKeyId = process.env['AWS_ACCESS_KEY_ID']
const secretAccessKey = process.env['AWS_SECRET_ACCESS_KEY']
const s3 = new aws.S3({
region,
accessKeyId,
secretAccessKey,
signatureVersion: 'v4'
})
exports.handler = async (event: any, context: any, callback: any) => {
let resp: Response
let putURL: string = ''
try {
const rawBytes = await randomBytes(16)
const imageName = rawBytes.toString()
var params = { Bucket: bucketName, Key: imageName, Expires: 60 };
var promise = await s3.getSignedUrlPromise('putObject', params).then(value=>putURL=value)
resp = {
statusCode: 200,
body: JSON.stringify({
URL:putURL
})
}
} catch (err: any) {
console.log(err.stack)
resp = {
statusCode: 400,
body: err.stack
};
}
return resp
}
I’m using in my project other netlify functions to do some other api requests and they are working just fine.
Used versions:
angular 14 as framework
netlify: 12.0.1
netlify-cli: 12.0.11
Thanks
