Yes! Once the transformation job has been completed, you can review the mapping in the returned job payload and our Lume dashboard. You can review, edit, and deploy the mapping pipeline from the dashboard. There are two ways to fix mappings. You can edit the target schema (e.g., make a required target field nullable) or manually override our mapping by giving the correct mapping value from the source data. I have also attached a Loom video showing this workflow: https://www.loom.com/share/95e47ead923d4911b647456174142e00
