KB5007039 - FIX: You encounter error messages 8114 or 22122 when performing change tracking cleanup

After you apply SQL Server 2016 Service Pack 3 (SP3) or SQL Server 2017 Cumulative Update 26 (CU26), and you run a change tracking cleanup stored procedure, sp_flush_commit_table_on_demand or sp_flush_CT_internal_table_on_demand, you encounter the following error:

Msg 8114, Level 16, State 1, Procedure sp_add_ct_history, Line LineNumber
Error converting data type numeric to int.

You might also encounter the following errors in the SQL Server error log:

DateTime spidNum Error: 22122, Severity: 16, State: 1.

DateTime spidNum Change Tracking autocleanup failed on side table of "table_name". If the failure persists, use sp_flush_CT_internal_table_on_demand to clean up expired records from its side table.

After you encounter this error, change tracking automatic cleanup can't clean up entries from the side table or syscommittab table.
