Tests fail on Serverless Functions

Reviewed on July 30, 2025

Problem

I get error messages when testing Serverless Functions using the Scaleway Console.

Testing Private Serverless Functions is not possible using the Scaleway console due to CORS limitations.

Change the visibility of your function to public. Public functions can be executed anonymously.
Make sure you have created an authentication token for your private function, then execute a curl request from a terminal, as shown below:
```
curl -H "X-Auth-Token: <YOUR_AUTH_TOKEN>" \ <YOUR_FUNCTION_ENDPOINT>
```

Still need help?
