Hi @vebaev
Unfortunately, the shared link is not very informative.
You can report the error to the support team using the following procedure:
click at any output of a failed job
click at Error icon, the one looking like ladybird beetle
provide description in the middle window (optional)
hit Report.
Alternatively, share the history in history menu and post URL here, so people can check what is going on.
Note that it is time of Galaxy Community Conference. There might be delays with replays.

Kind regards,
Igor
