Remote Attestation Process - problem with IAS response

Dalton_V_ · ‎08-22-2017

Hello.

I did the process of remote attestation in a NodeJS application. When I tried to do a post to IAS, with the main NodeJS modules for request, I received this error:

error: { Error: Parse Error
    at TLSSocket.socketOnData (_http_client.js:411:20)
    at emitOne (events.js:96:13)
    at TLSSocket.emit (events.js:191:7)
    at readableAddChunk (_stream_readable.js:178:18)
    at TLSSocket.Readable.push (_stream_readable.js:136:10)
    at TLSWrap.onread (net.js:559:20) bytesParsed: 195, code: 'HPE_UNEXPECTED_CONTENT_LENGTH' }

Searching about this problem, I found out that this is related to a malformed response from IAS, as stated in:
-http://stackoverflow.com/questions/35525715/http-get-parse-error-code-hpe-unexpected-content-length

-https://github.com/nodejs/node/issues/5754

-https://github.com/nodejs/node/issues/6517

As a workaround, I had to use a module based on curl. Can anyone please explain me if this format of the response from IAS could be "fixed" and avoid future problems with other developers?

Thank you.

Dalton, I will try to recreate this error of HPE_UNEXPECTED_CONTENT_LENGTH on my development environment to understand this issue better on when and how it can occur. A status update will be followed.
