问题
I wrote a small code in AWS-Lambda(Node.js) to send the file to some API. I am able to run the code but i am getting the upload error.
Error: Function Logs:
START RequestId: 08ad7fab-3658-11e8-8483-a7fbad976cb7 Version: $LATEST
2018-04-02T09:27:17.787Z 08ad7fab-3658-11e8-8483-a7fbad976cb7 upload failed: { Error: unable to verify the first certificate

END RequestId: 08ad7fab-3658-11e8-8483-a7fbad976cb7.
The code which i have written is :
console.log('Loading Function');
const fs = require('fs');
const request = require('request');
const url = require('url');
const https = require('https');
https.globalAgent.options.ca = rootCas;
var rootCas = require('ssl-root-cas').create();
// default for all https requests
// (whether using https directly, request, or another module)
require('https').globalAgent.options.ca = rootCas;
exports.handler = (event, context, callback) => {
var formData = {
// Pass a simple key-value pair
my_field: 'my_value',
// Pass data via Buffers
my_buffer: new Buffer([1, 2, 3]),
// Pass data via Streams
my_file: fs.createReadStream(__dirname + '/myfile.csv'),
// Pass multiple values /w an Array
// attachments: [
// fs.createReadStream(__dirname + '/myfile.txt'),
// fs.createReadStream(__dirname + '/myfile.txt')
// ],
};
var req = request.post({url:'https://abc.xyz.com:443/file/', formData: formData}, function optionalCallback(err, httpResponse, body) {
if (err) {
return console.error('upload failed:', err);
}
console.log('Upload successful! Server responded with:', body);
});
};When i am trying to run the same code locally, i am not getting any error even the module ssl is able to download all the certificates. The same when i am trying in AWS-Lambda , the code wont be able to download the certificates. I even tried in the Configure test with adding the JSON as rejectUnauthorized": false ,still not able to overcome with the error.
