No leader found for the Partition

Hi Forum,
We have been facing issue while deploying camunda using docker method.
The issue is that while we change the partition count to 3 and 4.
We are getting the statement “no leader found for the partition”. Are we missing something here. ? Does this mean we have incorrectly set the partition or something else ?
Configuration file for which this is attached below.
