Troubleshooting User Field Errors in Airtable Record Creation via n8n

It sounds like the issue is related to the way values are being provided for the User field when creating a record. In Airtable, user fields aren’t plain text; they expect valid collaborator identifiers (typically as an array of user record IDs) rather than just names or emails. When you retrieve tasks with “Get Tasks,” you see the User field populated with the proper structure that Airtable returns. However, when you try to create a new record and supply a value for that field, if it doesn’t match the expected format, Airtable will reject it.

Here are a few suggestions to resolve the issue:

• Verify the format – When creating a record, make sure you’re passing an array of valid user IDs (the same IDs that appear when you retrieve tasks) into the User field.

• Match the values – If you’re mapping fields automatically, double-check that the output from your previous nodes (or a lookup) provides the corresponding “user” identifier expected by Airtable rather than just the user’s name or email.

• Test with a static value – As a debugging step, try setting the field with a known valid user ID (wrapped in an array if multiple are allowed) to see if the node accepts it. For example, if a valid user ID is “usr123…”, pass it as:

  [ "usr123…" ]

Following these steps should help align the data with what Airtable expects for user fields during record creation. Let me know if you need any additional guidance!
