Troubleshooting "AADSTS90015: Requested query string is too long" error while accepting Bitbucket Cloud invitation using the Microsoft sign-in button

Summary

This knowledge base article will explain the issue users encounter while accepting a Bitbucket Cloud invitation using the Microsoft Sign-In button, resulting in the error message: "AADSTS90015: Requested query string is too long".

Cause

This occurs when the URL being used to authenticate with Microsoft Azure Active Directory (AAD) contains a query string that is too long. This error is commonly seen when trying to authenticate with AAD using a URL longer than the maximum allowed length of 2048 characters.

Solution

If you encounter this issue, there are two options you can try:

Option 1: Manually sign in to Bitbucket before opening the link:

1. Sign in to Bitbucket.org using the Microsoft sign-in option.

2. Make sure you are logged in.

3. Open the invitation link by clicking or copying and pasting it into a new tab.

4. You should see an option to accept the invitation to join the workspace.

5. Accept the invitation to join the workspace.

Option 2: Decode the URL to shorten it using a URL decoder:

1. Right-click on the "Accept my invitation" button and copy the link.

2. Go to a URL decoder tool like "https://meyerweb.com/eric/tools/dencoder/" or "https://www.urldecoder.io/".

3. Paste the copied link into the decoder tool.

4. The decoded URL will look like:

   1 https://id.atlassian.com/signup/invite?application=bitbucket&continue=https://bitbucket.org/account/signin/?next=https://bitbucket.org/invitations/account/<some string>&signature=<some string>

5. Remove the following part from the URL:

   1 https://id.atlassian.com/signup/invite?application=bitbucket&continue=

6. The shortened URL should look like this:

   1 https://bitbucket.org/account/signin/<....>

   ℹ️ If you don't want to use the suggested URL decoder, you can manually decode it yourself using URL Decoder
