Node app not picking up the DATABASE_URL env

I am trying to Node app that use Postgraphile which connect to a development database($7), but I am getting following error from Node app which is caused due to DATABASE_URL.

Error: Errors occurred during settings validation:
Setting 'connectionString': Expected a string, or for DATABASE_URL envvar to be set

But in env vars of node app component there is indeed the DATABASE_URL which is set to ${db.DATABASE_URL} which was automatically added when attaching the development database to the app.

I am confused what is going on here?

Hi @kaushalyap,

I’ll recommend giving the following a read:

Have you configured the Database URL in the APP-Level Enviroment variables?

Once you enter the bindable variable, click Save. The app redeploys.

You can check that the environment variable works by opening the app’s Console tab and running:

echo $<name-of-environment-variable>

Hello @kaushalyap

You can setup environment variables to set the DATABASE_URL

When creating an app, specify environment variables on the Environment screen. Click the Encrypt checkbox to obscure the variable’s values from all build, deployment, and application logs.

Hope that this helps!
