This is an error from Airtable, not miniExtensions. If the extension stopped working (what seems to be) all of a sudden, you can troubleshoot the problem by going through the following possible reasons. Before proceeding, make sure that you are logged in with Airtable using the account that integrated with miniExtensions before. Check this article on how to identify the account.
1. Base is missing from Airtable integration
Make sure that the Airtable integration includes the base that you are trying to access. You can learn how to update your Airtable integration in this article.
2. Invalid API Key
The user may have lost access. If the Airtable user that set up miniExtensions doesn't have access to the base anymore, the Airtable API key that was used to connect Airtable with miniExtensions will not be valid anymore. Therefore the connection between the two will become invalidated (unauthorized).
3. Read-only Access
Base level. Your Airtable account may have read-only access to the base (how?).
Table level permissions.
Field level. Some fields have restricted permissionsℹ️. Check the field configuration in Airtable. You need creator or owner permission (if you can't edit a record on Airtable, you won't be able to edit it on miniExtensions).
💡Tip: This might be the reason you encounter the error randomly/intermittently in the same form or child form. You have to find the field that has this restriction and adjust it accordingly.
4. Synced Table
You’re trying to set up the extension on a ‘Synced’ table to edit (read-only) fields.
