so that we can end up forwarding it to our engineering team.


Done. Where can I see statistics for fixes for the issue tracker? It would
be good to know, statistically, the average time-to-fix for issues. > It
would be best if you could provide us with a reproducible sample or a
description of any specific action that you are taking that is resulting in
this error so that we can attempt to reproduce it.


This only occurs in production, I guess because there may be very large log
strings, with a specific content -- I don't know what, as these strings are
not logged 😉 -- that breaks the Cloud Logging regex pattern.
