[mostafa4c]

var agent = new SyncAgent(serverProvider, clientProvider);
await agent.LocalOrchestrator.DropAllAsync();

return error
[DropAllAsync]..[InternalGetSchemaAsync]..[InternalGetTableSchemaAsync].Table:HR_empvacationdata..[SetPrimaryKeysAsync].Table:HR_empvacationdata..Table HR_empvacationdata does not have any primary key.

this Table:HR_empvacationdata not in Sync process
in 0.9.7 no error return

I am experiencing something similar (I think) after upgrade from DMS 0.9.7 to 0.9.8.
Calling await webServerAgent.RemoteOrchestrator.DropAllAsync(); now throws
[DropAllAsync]..[InternalGetSchemaAsync]..[InternalGetTableSchemaAsync].Table:scope_info_server..[FillSyncTableWithColumns].Table:scope_info_server..In table scope_info_server, the Column name sync_scope_name is not allowed. Please consider to change the column name.
