Apollo-client: How to prevent Apollo Client trying to parse HTML responses which are not in JSON format?

Created on 19 Apr 2018 · 2Comments · Source: apollographql/apollo-client

Intended outcome:
Called an Apollo Service which returns HTTP 403 error. Since the body response contains the following HTML, the client should just ignore the content.

<!DOCTYPE html>\n<html lang="en">\n<head>\n<meta charset="utf-8">\n<title>Error</title>\n</head>\n<body>\n<pre>Error: Forbidden</pre>\n</body>\n</html>\n

Actual outcome:
Apollo Client tries to read the HTML interpreting it as JSON and fails with error: Unexpected token < in JSON at position 0.

How to reproduce the issue:
Call any Apollo service with Apollo Client which returns HTTP code != 200 with the content of the HTTP response being in HTML format.

Question
I can work around this problem by wrapping all calls into a try { } catch() { } block, then reading out the status code, checking the type of the body response and handling the exception. However, I find this very cumbersome as I would have to do this with every call. Is there a way to globally configure Apollo Client to not try to parse the HTTP response body if it is anything else than JSON?
