Hi @mixelpix,
Welcome to the Zapier Community! Happy to help here.
This error usually appears when you are using an older version on an app integration -- in this case, the Airtable app integration (when you see a version number next to an integration name, it means a newer version is available).
I recommend checking the app version for the Airtable app you are using by going to your trigger/action step and then look for the part where you can choose the app & event. From there, check to see if the Airtable app has other newer version. Usually it will have a label that says ‘Latest’ next to the name of the app.
When you get a chance, give this a shot and let us know how it goes!
