Issues with triggering UpdateSchema Job on database system connection

Hi

I have a synchronization project (CSV Connector) which needs an updation of the schema.

Able to trigger the update schema through Synchronization Editor.

As though, we're able to trigger the update schema job for csv connection from object browser but getting below error when we tried to do the update schema job for the database connection.

Error:

Error executing script 'Event_UPDATESCHEMA'.

Error generation process step event UPDATESCHEMA.

Error generating process DPR_UpdateSchema.

Error executing prescript.

Job server connection information to cannot be detected.

Please help,

Thanks in advance
