1274957 - Network Monitor: 'Response' tab gives SyntaxError for valid JSON request

Status: RESOLVED WORKSFORME

(DevTools :: Netmonitor, defect, P2)

Description

[Jens]

Attachment: SyntaxError for json request

User Agent: Mozilla/5.0 (Windows NT 6.3; WOW64; rv:48.0) Gecko/20100101 /
Build ID: 20160519004038

Steps to reproduce:

1. Open Network Monitor
2. Open a valid JSON like http://nominatim.openstreetmap.org/search?q=135+pilkington+avenue,+birmingham&format=json&polygon=1&addressdetails=1
3. Click on Response tab

See screenshot.


Actual results:

SyntaxError: JSON.parse: unexpected character at line 1 column 1 of the JSON data. 
(BTW: Would be appreciated if error messages like this could be selected and copied, e.g. to do a quick google search or similar - now I needed to retype it manually)

Happens in Dev Edition and Nightly.

Maybe related to Bug 923856


Expected results:

Show formatted json.

Attachment: Console net monitor showing 'encoding'

Maybe it's an encoding problem? At least the console's net output under 'Response' only show garbage, see new screenshot

Thanks for the report!

I can also see the problem. Btw. the JSON Viewer (if enabled in about:config devtools.jsonview.enabled) works well so, it really might be just encoding problem.

I can't reproduce this problem in Firefox 65 (Nightly)

Closing, but feel free to reopen (or ping me) if you are still seeing it.

Thanks for the help!
