Migrating site, now getting Uncaught PHP Exception RuntimeException

I am migrating a site over to Pantheon which I have done manually.

Am getting the ‘The website encountered an unexpected error. Please try again later.’ screen and the following in the error log:

Uncaught PHP Exception RuntimeException: “Unable to determine class for field type ‘geofield’ found in the ‘field.storage.node.field_map’ configuration” at /code/core/modules/field/src/FieldStorageConfigStorage.php line 160

I have tried update.php etc but no joy. Any ideas what my next step to debug should be please?
