Hi, I am attempting to map data from a patient table to the OMOP Person table using Perseus, but the data is not being populated into the Person table after I execute the "Convert to CDM" operation. Despite no errors being reported during the mapping or execution process, the target OMOP table remains empty.

Here is the scenario and the steps I followed:

Source Table:

My patient table contains the following fields:
row_id (integer): Represents unique row numbers (e.g., 1, 2, 3...).
id (character varying): Represents the patient identifier in the source system.
bod (date): Represents the patient's date of birth.
Mapping:

I mapped the source fields as follows:
row_id → person_id (OMOP required field, integer, primary key).
id → person_source_value (OMOP optional field, varchar).
bod → birth_datetime (OMOP optional field, timestamp).
Screenshot of the mapping configuration in Perseus: [Attach a screenshot of the mapping, like the one you previously shared.]

Expected Result:

Data from the patient table should populate the Person table, with person_id, person_source_value, and birth_datetime correctly mapped.
Actual Result:

The "Convert to CDM" process completes successfully, but no data is inserted into the Person table.

Observed Behavior:
The target Person table remains empty even though:
No errors are reported during the mapping or execution.
The source data is valid, and the mapping configuration seems correct.
The id field's data type I specified 'varchar (50)' automatically changes to character varying data type.
