When the pipeline or any step is executed, a task is created, and it name will be taken from the decorator parameters. Additionally, for a step, the name parameter is optional : if not provided, the function name will be used instead.

It seems to me that your script fails creating the pipeline controller task because it fails pulling the name parameter. which is weird ... Weird because in the last error line, we can see that name !

I replaced local host with the host name of the server in the credentials
