INC_03020207 – History MV fails after adding new column to source PySpark MV

We are using a PySpark script inside Incorta to call an API and load data into a Materialized View (full load). Since loading this MV directly into a table is not feasible, we store the data in a history Materialized View (incremental mode) to maintain snapshots. When a new column is added to the source MV, the full load completes successfully; however, the incremental load of the history MV fails with INC_03020207 (schema mismatch) .
