There was an error querying for traces:
Unexpected end of JSON input

Hello, also seeing this issue here.

What happens is that the UI receive a 200 status code with no JSON body from the server part. The strange thing is that it seems caused by some particular spans. When querying for spans other than these particular spans, the UI displays them gracefully.

Even if some spans are corrupted, shouldn’t the server part at least return the valid ones to the UI?

Yep, service is populated in the left-had side form. Most of the Operations display a properly, but I have a few that don’t.

If you have the field populated, the “Find Traces” button enabled, and still get a request being made without the service parameter, then there’s definitely a bug in there…
