hi @knueser and welcome to our community
Did you check the contents of the ...\my.coveragexml file ? does it contain anything?
Also, did you read the Code Coverage is not shown in the SonarCloud.io topic? Could you follow the advice given there to diagnose your problem?
You can also read this answer for more info and tips here.
To be able to help you, we need the verbose logs of the END step. You can turn on the verbose output of the command (please run SonarScanner.MSBuild.exe begin /k:“MyProject” /d:sonar.verbose=true as the begin step). That is, add the /d:sonar.verbose=true parameter to the command.
Thanks, I found the log statement in our code and will update it.
