Troubleshooting Invoke-RestMethod with Bitbucket's API in PowerShell

When working with APIs in PowerShell, one common error is related to sending properly formatted JSON data. Recently, a user encountered a frustrating issue while trying to create a repository in Bitbucket using the Invoke-RestMethod command. The error message indicated that the project data sent to the API was not being recognized correctly. In this guide, we will explore this problem and provide a clear solution to ensure your API requests will be successful.

The Problem

The user attempted the following PowerShell command to create a new repository in Bitbucket:

However, the server responded with an error message stating:

This error indicated that although the user believed they were correctly creating a project object with a key, the server was not able to recognize the object as expected. The core of the issue lies in how PowerShell handles objects and the formatting required to communicate with APIs.

The Solution

To resolve the error, we need to convert the PowerShell object into a properly formatted JSON string before sending it as part of the API request. Here’s how to do this step-by-step.

Step 1: Convert PowerShell Objects to JSON

Instead of sending a PowerShell hashtable directly, we will convert it to JSON. This gives the API the correctly formatted payload it expects.

Create the Body as JSON:
Instead of the current method, use ConvertTo-Json to serialize the body object.

Convert Headers to JSON (if needed):
For API headers as well, ensure they are in the correct format if they contain complex types (not necessary in this case but good to keep in mind):

Step 2: Sending the Correct API Request

Now, with the JSON-encoded body, you can make the API call using Invoke-RestMethod without the previous error:

Key Takeaway

The primary takeaway here is to remember that when making API calls with Invoke-RestMethod in PowerShell, you need to ensure that your data is in JSON format. If it’s not, the API may not be able to interpret your request correctly, resulting in frustrating errors. Using ConvertTo-Json ensures that the data is sent in the required format for the API to process it effectively.

By following these steps, you can eliminate common errors caused by improperly formatted JSON in your PowerShell scripts and successfully interact with Bitbucket's API!
