Cannot get Log Reader Agent to run on Azure SQL Managed Instance

Question

I configured Azure SQL Managed Instance for transactional replication, it is a publisher with local distributor. I got it set up and the snapshot agent runs successfully, but the log reader agent is throwing errors:

The last step did not log any message! (Source: MSSQL_REPL, Error number: MSSQL_REPL22037)
Get help: http://help/MSSQL_REPL22037

Here is the output of MSlogreader_history table:

This is the command I used to add the log reader agent:

EXEC sys.sp_addlogreader_agent @job_login = '<login1>', @job_password = '<pwd>', @publisher_security_mode = 0, @publisher_login = N'<login1>', @publisher_password = '<pwd>'

Where <login1> is a Sql user with sysadmin privs.

I even addded -OutputVerboseLevel 2 to the log reader agent properties, but the output did not change.

Here is replmonitor :

Answer 1

This issue has been resolved - the issue is I was dropping/re-creating via scripts in our non-prod environment. When doing cleanup, I did not remove the replication Sql Agent jobs associated with the publication, so I had about 20 old log reader agent jobs existing/running. Once I removed all the obsolete jobs, it worked as expected.
