    I've been running into this issues as well. It's not ideal, but there's a temporary workaround. The problem is that the file with the custom function isn't getting properly included:
    - Select the problem shader graph in project window.
    - In inspector, select "View generated shader".
    - Copy full text to a new .shader file.
    - Manually add #include lines pointing to your custom function file.
