Failure to add a user to a group

I’m trying to add a user to a group with 379 members. Everything seems to work until I click Save, and then I get a red message “Invalid user: 2494”, and the group is not updated. Is there someway to find out which user is 2494, or is there another way to solve this?

This is indico 2.3.1

Thanks,

Chris

Maybe that user was deleted? Look for an entry with a little exclamation mark next to the icon:

PS: Please update to 2.3.4 as soon as possible.

Yes, that was it, there were 3 members who had been deleted.

Thanks,

Chris
