Executing a Data Flow where source object is from a Generic OData connection type.

The issue arises from a metadata unsync problem in the Data Flow.
The source object was changed, and Data Flow now expects an inexistent column from object.

1. Verify if there is a metadata mismatch between current Source Object and a new one being loaded from same Connection/Object.
2. Confirm that the source object loads same amount of fields.
3. If yes, make sure column from error is present in Source's metadata.
4. In case missing, verify if the OData service could re-include the missing column again, or re-design the Data Flow to remove the non-existing columns.
