Another meaningless spark error: Session is unable to register ReplId

Thank you for the reply.

In this case, I seem to be the first one to ever post about this message to the public internet.

Regardless if it is transient or not, customers need to understand the meaning of any error message.  We need to know if errors can be fixed in our own custom code or must be fixed in Microsoft's code.  We need to know if the fix will be considered a "workaround" or a "permanent" fix.    We need to know if retries should be done x3 times or x30 times.  We need to know if the problem is affecting all customer tenants, or if they are isolated to just our own customer tenant.

It is extremely unlikely that this is a "temporary glitch" which I will never see again.  I should mention that I've only been using Fabric Spark for a few days, and I've encountered many, many errors which are meaningless to me.  I have experience with other Spark platforms and in most cases we are able to google for an explanation about any error message.  In most Spark platforms the error messages can be fixed by correcting our own code.  However the bugs I'm seeing in this Fabric flavor of Spark seem to originate from Microsoft's home-grown extensions to Spark.  (like Livy, for example)

If you are able to interpret this error message or the callstack please let me know.  You could save me a LOT of time.  The Mindtree support cases take many weeks, while waiting on a response from the back-end PG.  I have started that process, but nobody from Microsoft has engaged with me yet.
