Problem when i create Function

I want to create a function in my Appwrite self-hosting but I get this error “Provider Error: Not Found”. My current version of Appwrite is 1.4.13

TL;DR

User is trying to create a function in their self-hosted Appwrite, but receives a "Provider Error: Not Found" message. They are using Appwrite version 1.4.13. They are asked about their deployment method and the runtime/language they are using. No solution is provided in the thread.
