Hi,

Thank you in advance for any assistance!

I have a job that is executed on schedule, and approximately once a day for the last few days, I receive this error message:

“The schedule deployment could not be executed after 1 attempts. Cause: Could not load job (status code: 500): Could not extract archive of workflow ‘_(redacted)_’ for _(redacted)_: Could not authorize client for workflow download. Information about schedule deployment: Name: _(redacted)_: \*_(redacted)_ Workflow path: _(redacted)_ User: _(redacted)_ Next execution: January 9, 2026 at 8:15:00 AM GMT”.

Apart from these occasions, the job is executed successfully.

Any idea about what might be behind this error?

Thank you!

How do you have the schedule set up - batch, Knime Pro or Business Hub (Server)? Is the problem random or every time the schedule is executed? Finally, if you’re running KAP 5.9, the batch capability is now in a separate extension.

Hi,

thank you for your reply!

The problem appears a few times randomly (once a day or weekly). The AP version is 5.2.5.

Thank you in advance!
