Supabase Edge Functions Function Not Found

What is Supabase Edge Functions Function Not Found

Understanding Supabase Edge Functions

Supabase Edge Functions are serverless functions that allow developers to run code in response to HTTP requests. They are built on top of Deno, providing a fast and secure environment for executing JavaScript and TypeScript code. These functions are ideal for building custom APIs, handling webhooks, or performing background tasks.

Identifying the Symptom: EF002 - Function Not Found

When working with Supabase Edge Functions, you might encounter the error code EF002: Function Not Found. This error typically manifests when you attempt to invoke a function that the system cannot locate. The HTTP response might return a 404 status code, indicating that the requested resource is unavailable.

Exploring the Issue: Why EF002 Occurs

The EF002 error occurs when the system cannot find the specified function. This can happen if the function name is incorrect, the function has not been deployed, or the endpoint URL is malformed. It's crucial to ensure that the function is correctly named and deployed in the Supabase dashboard.

Common Causes of EF002

The function name in the request does not match any deployed function. The function has been deleted or not yet deployed. The endpoint URL is incorrect or malformed.

Steps to Resolve EF002: Function Not Found

To resolve the EF002 error, follow these steps to ensure your function is correctly deployed and accessible:

Step 1: Verify Function Name

Ensure that the function name in your request matches the name of the deployed function. Check the Supabase dashboard under the Edge Functions section to confirm the function's name. The function name is case-sensitive, so ensure it matches exactly.

Step 2: Check Deployment Status

Navigate to the Supabase dashboard and verify that the function is deployed and active. If the function is not deployed, you can deploy it using the Supabase CLI:

supabase functions deploy <function-name>

Replace <function-name> with the actual name of your function.

Step 3: Validate Endpoint URL

Ensure that the endpoint URL is correctly formatted. The typical format is:

https://<project-ref>.supabase.co/functions/v1/<function-name>

Replace <project-ref> with your project's reference ID and <function-name> with the name of your function.
