Error uploading workflow 5.5.1 on Hub

Feedback & Ideas

Hi!

Today, I updated my local KNIME installation as usual, and at the end of the day, I uploaded the workflow.

When I tested, to my surprise, I received this error message:

After conducting extensive research, I found that version 5.5.1 is not considered “production” on Hub for Team accounts. Therefore, I’ll likely need to downgrade my local installation to 5.5.0 to run the new workflow version.

Fortunately, I have version control and I could roll back my hub to the previous version, but without the last improvements.

Does anyone have any additional information?

Thanks.

EDIT: Knime 5.5.1 isn’t released yet and sometimes backwards compatibility is, especially when nodes receive significant updates, difficult to manage.

Just noticed 5.5.1 was released …

Prior to testing a new version of Knime I usually do a full backup of my workflow and test on a dedicated machine (or VM).

Hi @mwiegand

I thought that my KNIME was configured to take just the released versions.
I didn’t understand what happened.
But now Hub is on 5.5.1. I’ll check it.

Thanks.
