Problem

-- by default, while deploying a flow from mapping services, the name of the container is MAPSERVICE.<FLOW Name>

-- MAPSERVICE is called the Entity name

-- it is possible to change the Entity name by changing the value of "-Dms.entity.name" in MappingServices.ini
Ex : -Dms.entity.name=DEMO

-- but for some reason, the entity name does not reflect the name set in the ini file

Resolution

* the name of Mapping Services executable file must match the name of the ini file

* it is likely that the name of the executable file has been modified from MappingServices.exe to <something else>.exe

* rename the Mapping Service executable file back to MappingServices.exe
