Hi,

While disconnecting the database using `DISCONNECT USING THIS;` inside the transaction object, we are getting the following error:


PowerServer[0]
Failed to commit because there is no available database connection or transaction

fail: PowerServer.Api.ServerApiController[1003]
CommitAndCreateTransaction(...):
{
  "IsSuccess": false,
  "AppName": "laboratory",
  "NameSpace": "Laboratory",
  "Type": "Commit",
  "TransactionName": "sqlca",
  "SessionId": "...",
  "TransactionId": "...",
  "ErrorCode": -1,
  "ErrorMessage": "Failed to commit because there is no available database connection or transaction"
}
```

Before calling `DISCONNECT USING THIS;`, we verified that the database connection is active and valid. However, immediately after triggering the disconnect, PowerServer attempts to call `api/ServerApi/CommitAndCreateTransaction`, which fails with the above error.

The issue is also confirmed in the Fiddler trace, where the `api/ServerApi/CommitAndCreateTransaction` API call returns this error during the disconnect operation.

Could you please provide a fix or recommended approach to overcome this issue and properly disconnect the database connection in PowerServer?

Sample connection

atrans_obj.DBParm="CacheName='" + Trim(ars_cachename) + "',LongConnection=1,TrimSpaces=1"

Other Info

"ConnectionType": "SqlServer",
 "EnablePooling": true,
 "MinPoolSize": 0,
 "MaxPoolSize": 100,
 "ConnectionLifetime": 0,
 "ConnectionTimeout": 15,
 "CommandTimeout": 3660,
 "SecurityOptions": "encrypt=False;trust server certificate=True",
 "OtherOptions": "multiple active result sets=True;Pooling=False",
 "DynamicConnection": false
