Does it throw an error? I doubt this is related to Railway itself but I can help you investigate this.

If the repo is public I can take a look

https://github.com/thomasvmc/shakespeare

Does it throw any type of error?

i would have to start it again but i think it was every request to gemini not working

the first error was getting refresh token

oh wait its still on

I just don't get that its identical to my local setup and it doesnt work on railway

it doesnt crash just sends the error

Hmmmm code seems fine, try replacing the chat.sendMessageStream to just chat.sendMessage

And make sure you've properly set the environment vars on Railway

Add some type of logging on startup to check if the env vars are really there

Ive already submitted this can't change it

What do you mean you can't change it?

unless i can make changes on railway outside of github

its an assignment

for school

Through the CLI, you can clone the repo and do a railway up

https://docs.railway.com/guides/cli

alr

Another weird thing I spotted is that you send an empty object to GoogleGenAi
e.g: const ai = new GoogleGenAI({});
Maybe try explicity sending the API key there

const ai = new GoogleGenAI({
  apiKey: process.env.GEMINI_API_KEY,
});

its like that in the documentation they say it gets the token from the environment but ill try adding it to see if it helps

does it have something to do with that its on railroad because this literally works locally

i already copied and pasted the gemini token a few times so i dont think thats it

Now I'm sure it's related to the env vars

are you hardcoding it or using env vars?

are they properly set on your service variables tab?

wait

i think i see it lol

it should be key

yep

i cant believe i didnt see that

and it works now thats so stupid

that's more common than you think lol

is everything working fine now?

yep

nice, can I mark this thread as solved?

yep
