Problem

Closes #33704

Changes

When calling the local evaluation endpoint with the Feature Flags Secure API key, the permission check was failing.

https://github.com/PostHog/posthog/blob/34f74870798a58964791a95785acca79a9fc4558/posthog/api/routing.py#L98-L117

The permission check that was failing is the ProjectSecretAPITokenPermission, and it was because the request.resolver_match.view_name was not in the list of values.
