Hey there! We've found the following might help you get unblocked faster:

• 📚 Set a Start Command

• 🧵 Service Private Variable Reference

• 🧵 Set environment variable in config as code with railway.toml

If you find the answer from one of these, please let us know by solving the thread!

Ok so I solved the problem putting my variable reading into a function, in case this help future use case:

Before I have:

fernet = Fernet(os.getenv("MASTER_KEY").encode())

This line detect MASTER_KEY as 'None' as it was executed on runtime as it's a variable

After:

def get_fernet() -> Fernet:

global _fernet

if _fernet is None:

master_key = os.getenv("MASTER_KEY")

if not master_key:

raise RuntimeError(

"MASTER_KEY is not set. Define it as an environment variable."

)

fernet = Fernet(masterkey.encode())

return _fernet

This is ok as it's a method and call after runtime when Variable as setup

Ok its working at this tep but when the get fernet is call later (on a API call for exemple) its still failing... I need to explore more solutions, if you got more ideas... please

Hey! I’m glad you’ve made some progress. If the variable is still not loading correctly during the API call, you might want to try adding some detailed logging to see exactly where it fails. Also, double-check the configuration and make sure that the environment variable is properly set before the function is called. If you need more help, feel free to share any logs or additional details, and we’ll figure it out together. Keep going, and I’m here to help!

Seem that restarting the service manually reset all variables / build and so on and now its working (by magic xD)...

So solution on using a method seem to work but we have to take care when railway automatically build after a git push as it seem that this redeploy didn't take in account the rebuild itself.
