I am using nodejs as a backend and the config plugin with it to get the access to the Railway envoironment variable.
However, I am unable to get the variable from after adding it to Raiway variables as it says the varaiable not found.

just as a test, are you able to access the variable with process.env.variable_name

It worked with process.env, as we were using config module however, it was working in past now it is not working.
Strange 😕

this would be an issue with the code then, please look into the documentation for the config module
