@skarllot stryker by default uses the branch called master for the since feature. Your repo does not have a master branch. You should set the target to main instead.

@skarllot

The reason you didn't hit this issue before is because since was never actually enabled in your repo due to #2706. This was recently fixed which enabled since and caused your pipeline to stop working.

Please let me know if you have any other issues after adding the since compare target.

Enabling since doesn't make it always run only for changed code?

Enabling since doesn't make it always run only for changed code?

It does, but there was a bug where since was not enabled implicitly by creating the object in the config file (instead you had to set since.enabled to true). That has now been fixed so now since is actually running on your project. If you read the issue I linked I think it will be more clear what went wrong before.

I updated the issue tags to reflect this it is not an issue per se, but documentation/error messages could be made more helpful
