Hi,

I set some application environment variables based on System’s environment variables in config.exs file like this:

And access it from DevicePlug module like this:

https://github.com/rainlab-inc/cothings/blob/master/lib/coliving_web/plugs/device_plug.ex#L19-L24

While I get access these values properly from another modules without problem, for example:

but I get error in DevicePlug module and it returns “false” as string instead of a boolean variable. Why?

Here’s a full stack error log:
