Understanding the 405 Error

The 405 Method Not Allowed status code indicates that the server recognizes the request method (like GET, POST, PUT, DELETE, etc.) but that the method is not allowed for the requested resource. This can happen for several reasons:

1. The API endpoint is configured to accept only certain HTTP methods.
2. There may be a typo or mismatch in the method specified in your Angular service.
3. The server might have restrictions based on authentication or permission settings.

Common Scenarios Leading to 405 Error
