DemistoException: Failed to parse json object from response

bowesmana — Mon, 17 Jun 2024 06:16:29 GMT

I'm making a request in an integration to an external API

return self._http_request( 'POST','export/download', headers={'accept': "application/octet-stream", 'content-type': "application/x-www-form-urlencoded"}, data=payload)

and I get back a data stream - it's looks like it should be a JSON array, but is actually not, it's simply a long list of separate JSON objects, e.g.

{"id":1} {"id":2} {"id":3}

so I get the error

File "<string>", line 66, in export_download File "<string>", line 9423, in _http_request File "<string>", line 9527, in _handle_success File "<string>", line 9545, in cast_response DemistoException: Failed to parse json object from response: b'{"id":"aaaaa","bd.hostname":"host1.bla"}\n{"id":"bbbbb","bd.hostname":"host2.bla"}\n

and so on...

How do I stop Demisto thinking this is a JSON object. - Line 66 is the one shown

After much digging, I found you need to set resp_type on the request - not sure why there is no simple documentation on the class, but just needed to add the following to the request

resp_type='text'

Had to eventually find the option here
