Can't Delete User on Locally Deployed Supabase: 'Method Not Allowed' Error
Problem
Discussed in https://github.com/orgs/supabase/discussions/32900 <div type='discussions-op-text'> <sup>Originally posted by thejufo January 18, 2025</sup> Context: I've recently deployed Supabase locally on my machine, everything worked great until I tried to delete a test user in Supabase Studio `http://127.0.0.1:54323` auth section. Problem: When I attempt to delete the user, I get this error message: "Failed to delete selected users: API error happened while trying to communicate with the server.". After digging into it a bit, I noticed this seems to be related to the Studio itself. Here's a screenshot of the request: <img width="1512" alt="Screenshot 2025-01-18 at 12 50 47 PM" src="https://github.com/user-attachments/assets/9d077058-0940-4e3b-9df4-1a7f53b164d3" /> What I’ve Tried: I dug deeper into the source code and found where the delete request is handled. From what I can tell, it should work, but for some reason, it's not, Here’s the code snippet: <img width="857" alt="Screenshot 2025-01-18 at 12 52 13 PM" src="https://github.com/user-attachments/assets/dab1ba22-670d-4294-8016-a0bb573b706b" /> Question: Does anyone know what’s going on here? Is there some configuration I missed, or could it be a bug? I’d really appreciate any advice or ideas on how to fix this! </div>

1 Fix
Fix 'Method Not Allowed' Error When Deleting User in Supabase Studio
The 'Method Not Allowed' error occurs because the delete request to the Supabase API is not being properly routed or is being blocked due to incorrect HTTP method usage. This can happen if the API endpoint for user deletion is not set up to handle DELETE requests correctly or if there are misconfigurations in the local Supabase deployment.
Awaiting Verification

- 1
Check Supabase API Configuration
Ensure that the Supabase API is configured to accept DELETE requests for user deletion. Verify that the endpoint for user deletion is correctly defined in the Supabase API settings.
bashcurl -X DELETE http://127.0.0.1:54321/rest/v1/auth/users/{user_id} - 2
Inspect Supabase Studio Source Code
Review the source code of Supabase Studio to ensure that the delete request is being sent with the correct HTTP method. Look for the function that handles the delete action and confirm it uses the DELETE method.
typescriptconst response = await fetch(`/api/users/${userId}`, { method: 'DELETE' }); - 3
Update Supabase Dependencies
Make sure that your Supabase installation is up to date. Run the following command to update your Supabase dependencies, as bugs may have been fixed in newer versions.
bashnpm update supabase - 4
Check Network and CORS Settings
Verify that there are no network issues or CORS (Cross-Origin Resource Sharing) restrictions preventing the DELETE request from being sent. Ensure that your local environment allows requests to the Supabase API.
bashCheck your browser's console for CORS-related errors. - 5
Test User Deletion via Postman
Use Postman or a similar tool to manually send a DELETE request to the user deletion endpoint to confirm that the API is functioning correctly outside of Supabase Studio.
httpDELETE http://127.0.0.1:54321/rest/v1/auth/users/{user_id}
Validation
To confirm the fix worked, attempt to delete a user again in Supabase Studio. If the user is successfully deleted without any errors, the issue is resolved. Additionally, check the network tab in your browser's developer tools to ensure the DELETE request is being sent and received correctly.
