export const PORT = process.env.PORT || 3000
export const DBHOST = process.env.DBHOST || 'localhost'
export const DBUSER = process.env.DBUSER || 'root'
export const DBPASSWORD = process.env.DBPASSWORD || ''

export const DBPORT = process.env.DBPORT || 3306

export const pool = createPool({

This is my code, and the env variables of Railway have the same name…

This is the error

Is this error from the build or deploy logs?

Have you tried console logging those variables?

This error is ocurrs when I try to query the database

Yeah, I've tried console logging those variables and the variables has the default value, not the process.env.VAR value

Please try to answer all questions I may ask in a comment.

From the build

Please confirm that with a screenshot.

Sorry currently is from the Deployt logs sometimes appears in it, but not now, but the error is here from the API client

Screenshot of your service variables, please.

Hello, sorry Brody, my internet dies and I can't continue with you…

You haven't deployed the changes, so of course you aren't going to be able to read them in code!

Oh..my bad, well I'm new in Railway and in general this is my first try to deploy an API. How can I do that?

Click the Deploy button.

Okay but I've did that and the error continues…

Screenshot of your service variables, please.

The service shows "5 changes, edited" How did you tell me, I've saved the changes, but I just clicked the Deploy button and the message still showing

Screenshot of your service variables, please.

Here..

sorry

You haven't deployed the changes.

Yeah…but I just clicked the deploy button in the deployments section and nothing happens

Is this the correct button?

No, that says redeploy. Click the Deploy button that appears above the project canvas.

Sorry brody I feel so fool, look my interface…I can't see that button

Well good news, it's not your fault for not seeing it, its your browser's fault, please open your project up in another browser, then you will see the Deploy button.

Man! you saved my life, thank you so much!

What browser where you using?

Chrome was the problem, I installed Brave and the button appears

Thank you Brody, you are a crack!

I use Chrome, it must have been some extension you had interfering with something.
