I registered my

ContainerTasks

with

pyflyte register -p myproj -d devel flyte/my_workflow.py

so far and it worked fine. Now I added one Python task, but that one fails with

Pod failed. No message received from kubernetes.

[a9lcdpfc5ldtrh9tlqf8-fl6pvdgq-0] terminated with exit code (1). Reason [Error]. Message:

I don't get what is wrong here... I can see that the file is in the package..
