Developers are encountering a route not found error when trying to use functions on a self-hosted instance of version 1.5.4 running on docker. The error message suggests checking the API docs. The problem might be related to the executor setup or endpoint configuration. Check if the executor is correctly pointing to the external domain with the endpoint `/v1`, and ensure it's not using any localhost references. Additionally, ensure that all necessary configurations, like Github integration and domain settings, are correct.
