    POST        /v1/nodeb/
    Output

The warning message come from following block of codes. try: response_body = response.json() except ValueError: response_body = response.text if response_body: logger.warn( "Response body content is not JSON. "

• "Content-Type is: %s" % response.headers["Content-Type"] ) If we're going to support more data format, so the Json validation should be executed if response data is Json. If not, we need to skip validations.

Thanks, DoanhPoPu

Is there a way i can remove this WARN from my tests ?

[DoanhPoPu]

We need to ask owner @asyrjasalo to change the log level to info (Change logger.warn --> logger.info) It will NOT show into the robot results

[asimell]

We'll probably add a keyword or other customization option to change the log level for the warning.

This has been implemented and merged to Eficode fork of this repository. We'll create a release PR to this repo once we get the release content ready.
