Workflow invocation scheduling failed - Galaxy EU

Dear Admins,

I have been running a certain workflow with my galaxy eu account for the last 3 days without problems. Today I tried to run it again but I get the following message: “Invocation scheduling failed - Galaxy administrator may have additional details in logs.”
I have no more additional information, sorry. The only thing I can share is that the workflow is not automatically recognising my input (paired collection) as it was doing the previous days.
Any help or explanation would be much appreciated.

Hi @Alan

The best advice would be to try again now, especially since this data and workflow was working previously.

And … if it seems that the data is still not being recognized, maybe create or copy that starting data into a new history, and try from there? That resets all of the history + dataset metadata.
