Fixing Unhandled Exception: 422 in Flutter's Airtable Integration

If you're working with Flutter and Airtable, you might have encountered the frustrating Unhandled Exception: 422 error while trying to update records in your Airtable database. This issue can lead to confusion, especially when basic operations like fetching and deleting data seem to work perfectly. In this guide, we'll break down the problem and provide you with a clear solution to help you get your Airtable updates functioning smoothly.

Understanding the Problem

The 422 Unprocessable Entity error indicates that while the server understands the request, the data structure sent in the request could be incorrect or incomplete. Specifically, when trying to update a record, you must follow the correct format specified by Airtable's API.

In your case, the error occurs when you attempt to use the record ID directly in the URL and overlook including essential headers and the correct structure in the request body.

Steps to Fix the Update Issue

1. Do Not Put the ID in the URL

Initially, your update request includes the record ID in the URL. For updating records in Airtable, you must modify your approach by sending the ID in the request body instead. This change is crucial for a successful update.

2. Add Content-Type to the Headers

Another essential aspect is specifying the Content-Type in your request headers. The Airtable API expects the Content-Type to be set to application/json to properly process the incoming data.

3. Update Request Body Format

Instead of sending the content directly as you did before, you need to send a structured body that includes records, along with their id and fields. This is where you specify the fields you want to update.

Here is an updated code snippet using the above recommendations:
