What does the 404 Error mean in Supabase when attempting to utilize RPC?

edit

The 404 Error in Supabase when attempting to utilize RPC means that the requested resource is not found on the server. This can happen if the endpoint for the RPC call does not exist, or if the server cannot locate the function or procedure being called. It is important to ensure that the RPC endpoint is correctly defined and that the function or procedure being called exists before attempting to make the RPC call.
