1006 Expected HTTP 101 response but was '426 Upgrade Required'

[phucbienvan]

hello,
I have a function called getPreSignUrl using SignatureV4 to get a presigned URL. However, when I provide this URL to the app, it throws an error with the message "1006 Expected HTTP 101 response but was '426 Upgrade Required'". Can you please help me with this issue?

async getSocketPreSignUrl() {
        const signer = new SignatureV4({
            credentials,
            region: AWS_DEFAULT_REGION,
            service: 'iotdevicegateway',
            sha256: Sha256,
        });

        const presign = await signer.presign(socketRequest, {
            expiresIn: 360000,
        });

        return formatUrl(presign);;
    }

const { HttpRequest } = require('@aws-sdk/protocol-http');
const { IOT_ENDPOINT } = process.env;

const socketRequest = new HttpRequest({
  protocol: 'wss',
  hostname: IOT_ENDPOINT,
  path: '/mqtt',
  method: 'GET',
  headers: { host: IOT_ENDPOINT }
});

module.exports = socketRequest;
