jhipster - can't run local dev profile after deploying app to Heroku - postgresql

Question

After using the jhipster generator, I am able to successfully run the app on my local webserver with a local PostgresQL. I managed to deploy it to Heroku as well, but now when I try to run it locally in IntelliJ (as I have before deployment), (selecting 'dev profile', clicking on spring-boot:run) or running the Application main method,
I receive the following error (Heroku Database url is not configured):

Answer 1

It is because of this error and it has been fixed in the latest version.

Answer 2

From the first line in your logs, the Heroku database URL is not configured
Caused by: org.springframework.context.ApplicationContextException: Heroku database URL is not configured, you must set --spring.datasource.heroku-url=$DATABASE_URL
Hopefully the following example will help:
