Service URL ENV variable is empty

The variable for a static URL of one of the services is empty (despite having a domain associated with it) - other services (and env variables) who are dependent on it are failing.

Variable name: RAILWAY_SERVICE_MPC_API_URL

f568f607-e4d1-4517-ba1a-537dc9a8be86

can you send a browser screenshot of your project

what kind of screenshot?

railway project?

bruh

full screenshot of your browser window with the railway project in question open

and what service is trying to access RAILWAY_SERVICE_MPC_API_URL

docs mention the static url env vars to be RAILWAY_{serviceName}_STATIC_URL

while the env variable is actually RAILWAY_SERVICE_{serviceName}_URL

i know, i dont understand that either RAILWAY_SERVICE_MPC_API_URL would be correct

the mpc service is trying to get the RAILWAY_SERVICE_MPC_API_URL

it is correct -it's just an empty string

do note that it worked - but since yesterday it's reporting as empty string

okay now what exactly is the mpc service?

mpc service is a web client service (nextjs app)

can you show me how you are accessing the variable in code

note that I do have the RAILWAY_SERVICE_MPC_API_URL variable provided - it's just that it's empty string

variable exists...

is that an .env file?

that's from the app

it's a dump of the env vars

while running on railway?

the project doesn't have .env vars in the git repo

while running on railway?

yes

ssr next app?

yea

next13

dont variables have to be prefixed with something?

like NEXT_

mpc-api is just an express app

it also has these variables

also empty strings

like NEXT_

NEXT_PUBLIC_ if you want them on public

e.g. front-end

any env variables that are not prefixed are available on the server

im sorry i cant reproduce this
https://utilities.up.railway.app/env-vars

you must be overriding them or something

Overriding them? nope...

they're just empty string vars

i think it's a bud on railway's side...

im sorry i cant reproduce this

Yes, because it should work - but since yesterday it just doesn't

bud=bug 😄

deploy an absolute bare minimun nodejs service, no framework, nothing, just index.js and package.json and inside that index.js file simply put

console.log(process.env);

how do I see the console log after deploying?

Done

vars are empty but that's because the PR env domains are empty - so it makes sense

added domains for the services

and rebuilding the test

now with domains set, RAILWAY env vars are still empty:

remind me, is this the first time you mentioned this being a pr environment?

it happens on non-pr envs

now after rebuilding with domains set the vars aren't empty

show me the code behind these printouts please?

index.js:

console.log('process.env:', process.env)

scripts.start/build are both set to node index.js

can you share the repo for that?

no, sorry

it's a simple nodejs with package.json and index.js as requested

you mean to make a public repo with that code?

id like to see the exact code that made this output

this helps? xD

the vars arent empty?

after rebuilding - no, aren't empty

filled correctly

but on production env's they are empty

despite having domains set

okay will flag team

🙏

thank you!

sorry it took so long to get to this point, i just had to be sure it was on railway's end

all good! looking forward for their reply

👋

Hey! Sorry for the delay here. Can you try re-deploying the env-vars test service? I wanna see what happens under the hood

redeploying now

deployment id: a7a2cd62-8cbe-4707-a5a9-acda79551715

interesting, could you try re-creating a new service for this? I'm wondering if the env vars we're picking up is stuck in a previous state prior to service creation

e.g. remove the service and add it from scratch?

yep

running

you can see that for the production env all the RAILWAY_SERVICE_MPC_*_URL are empty strings

staging as well

if it's of any help - it seems that the auto-generated domains are correctly populated

in the env vars, that is

then what isn't being populated

all the other services

redeployed - env vars for service urls are empty 😦

you can see the services (on the left) do have URLs, but the env vars echoed in app are empty...

I can confirm. Going to raise this up, thanks!

Thanks!
