This has noithing to do with too long exception. This is no exception. Just a Session ID and the above error message.
Look at the comment section of your Blog. Another user also reported about August Gateway update causing this error:

Community SupportHi , gururajhs
Are you facing a error of not being able to edit dataflow with Mashup_too_long exception?
This may be related to a known issue and the fix should roll out to all regions by this week.

Thanks for pointing to the august gateway link. We also using august version of dateway. The issue could be related to August version of on prem Gateway. I have also raised support ticket with Microsoft support team. I will keep you posted once I hear back from support team.
