On the new version 0.23.3 I get an error:

there is no error when rolling back to 0.20.1.
Install via pip install grafana-wtf.
Ubuntu 24.04.2 LTS

Hi Igor. Thanks for reporting the problem with 0.23.3. May we also ask you to validate if 0.23.2 or another previous release newer than 0.20.1 still works, so we can better narrow down where the error has been introduced?

Can you also tell us which Grafana version you are using?

Ah right, the log includes it:

Grafana version: 12.1.1

[IgorOhrimenko]

I have checked all versions 0.23.X and they all crash with a 404 error. However, version 0.22.0 works fine.

[amotl]

Thank you very much. I can't spot any obvious culprits in the release notes for 0.23.0, so we will need to investigate. Maybe you can spot anything suspicious in the diff per 0.22.0...0.23.0 what we don't see?

On the other hand, maybe the built-in cache was playing tricks on you when probing different versions of grafana-wtf? Please make sure to use --drop-cache to make this a non-issue.

[IgorOhrimenko]

I also found that there is a consistently repeating 404 error at 0.22.0 when using the "--concurrency=1" parameter, while using "--concurrency=2" there are no 404 errors.

grafana-wtf find someText --concurrency=1 --drop-cache

[amotl]

Indeed that change to use --concurrency=0 by default has been included into v0.23.0 with GH-181, thank you very much. I wonder why the integration tests did not catch this regression?

[amotl]

Following your observations, I figure grafana-wtf v0.23 might also work on your end when using --concurrency=2 or higher?
