Have you added MONGO_URI to your service variables on Railway?

Hello Yes,
I gave an example of what is showing up in the railway variables I created in the question above. It is very similar excluding my actual user name and password. Also thanks for the quick response

Can you show me the code you are using for mongoose?

// connect to db
mongoose.connect(process.env.MONGO_URI)
.then(() => {
// listen for request
app.listen(port, () => {
console.log('Connected to DB and listening on PORT ' + port);
})
})
.catch((error) => {
console.log(error)
})

not sure if a picture would be better

Please use code blocks when sending code.

Are you committing your .env file to GitHub?

Sorry about the code brackets. didn't know how to do that in this forum.
I didn't commit the .env file. that is in my .gitignore file

Code blocks here are done the same as any other forum.

Let's see your service variables.

Here is screenshots of both:

You aren't using typescript right?

No

Well I'm out of ideas for now, maybe if you shared your repo something might stand out.

sure:

Hmmm, not seeing anything stand out.

Unfortunately I had to go to a different hosting provider and it worked without issues!

This definitely wouldn't be a platform issue, but it is odd.

Had the same issue kind of with my golang project. The only thing I can think of is I had a newer version of Go than what was allowed on the platform at the time. I know it sounds weird, but It seemed to work on older versions.

I use Go 1.22.2 on Railway without issue.

FYI - I came back this morning and fixed the issue. it was so simple. LOL. railway had something on the left that told me they made changes and I need to update it. So I pressed it and when it updated the server was fine after that. No more error message. /cry

Ah I should have caught that, my bad, I now see the blue unsaved changes in your screenshot.
