ObjectScript: Cannot Read OpenId, Result Doesn't Display

the date format is most suspicious to me.
in SMP you can set it to
- Logical Mode  >>>  66453  like +$horolog
- Display Mode  >>> 2024/03/25    as you did. It is depending on default display settings.
- ODBC Mode    >>>  2024-03-25

Without seeing the entire method it is hard to tell.  Accepting that you have proven that the data is being retrieved I would look for issues with how it is being passed on.   The GetMasterOPDataExecute method of a custom query only does setup for the query.  Tasks such as initialization or defining a SQL cursor (if that is what you are using).

The GetMasterOPDataFetch method is what will return rows of data.  If this value is needed at that point you should include it in any information provided in the qHandle parameter.

In case you are not familiar with this I am including a link to the documentation for custom class queries.

Defining Custom Class Queries

Depending on your implementation you can 

• If using %SQL.Statement set %SelectMode accordingly
• if using the old %Library.ResultSet, set RuntimeMode accordingly

in your method code.
