Hi @rolandmosimann - We tried reproducing the error at our end, but unfortunately could not.
Both the workflows (Test & workaround) provided above completed successfully without error.

Please see the test run for the test workflow and workaround workflow.

Kindly, Let me know if you are still facing the issue, else we can close the same.
Thanks.
