Hello @geoffatsource, first of all, welcome to the community!
The Airtable import is currently a bit limited: it’s in the Beta stage and the functionality is less stable, some imports may not work properly. But with all the community feedback, we plan to polish the feature very quickly 
Regarding your particular case: we were aware of this bug and it’s already fixed in the hosted version on baserow.io. There is a small delay with the self-hosted versions (including Docker one that you’re using), but a big bunch of errors will disappear with the next release which is expected to be next week. We can ping you as soon as new changes are available, so we could test the Airtable import again with you together. What do you think?
