I have a mix release container, when i do Application.get_env(:logic, :api_key) i have the correct value, but when i do
@headers [KeyId: Application.get_env(:logic, :api_key), “Content-Type”: “application/json”], it says that the KeyID value is nil?
Module attributes which use the at-symbol like this are strictly compile-time values and will fully/immediately evaluate any function calls they are written to include as they compile, including
Application.get_env. Since you’re not populating that value until run-time, it will indeed be nil.
The solution here will probably involve adding a new function in this module that wraps
Yes, it works, thank you for the clarification!
