Solving the Unknown parameter(s): fieldData Error When Accessing the Filemaker API Using Flutter

When working with APIs in Flutter, you might run into various issues that could hinder your progress. One such problem is accessing specific calls to the Filemaker API, particularly when dealing with field data. Many developers have experienced the frustration of encountering errors that seem perplexing or cryptic. In this guide, we’ll explore a common issue related to the Filemaker API and provide a straightforward solution to overcome it.

The Problem

You may find yourself trying to access the fieldData field in the Filemaker API but running into the following error:

This error can be frustrating, especially if other requests are working as expected. Let's break down the situation that leads to this error and how you can resolve it.

Understanding the Error

The error code 960 indicates that the Filemaker API does not recognize the fieldData parameter. This usually means that the structure of your request is incorrect. To make matters more complicated, the method you use to send the request is crucial for proper communication with the Filemaker server.

The Solution

After investigating the issue, we found the solution lies in the method used to send the request to the Filemaker API. Instead of using the postUrl, you should use the patchUrl method. Here's why and how to do it.

Step-by-Step Explanation

Change the Request Type: The Filemaker API requires a PATCH request when accessing and updating the field data. By using patchUrl, you align with the expected behavior of the API.

Update Your Code: Modify your existing code as follows:

Why Use patchUrl?

API Specifications: Understanding the Filemaker API's requirements is key. They specify that field data modifications should be made through a PATCH request, which indicates partial updates to a resource.

Error Resolution: Switching to patchUrl resolves the unknown parameter error. The Filemaker API will now correctly interpret the fieldData parameter and process the request.

Conclusion

By revising your request method to patchUrl, you will successfully communicate with the Filemaker API and eliminate the frustrating Unknown parameter(s): fieldData error. Encountering issues with APIs is common, but with the right approach and understanding, you can effectively troubleshoot and solve these problems.
