Basic CRUD App with Angular 7.0 and Spring Boot 2.1: Invalid value for 'client_id' parameter

Hi Matt,
I need to create a WebApp with Angular 7 + Spring Boot 2, and being a rookie ==> I just downloaded from Github and followed the instructions from Build a Basic CRUD App with Angular 7.0 and Spring Boot 2.1.
The Webapp’s login page is loaded, but after I click on the Login button I get a Bad Request (400)
for the authorization request (authorize?client_id=0oa …), telling me in the JavaScript console error.errorCode: invalid_client, error.description: Invalid value for ‘client_id’ parameter.

Have you got any idea what can I do to get rid of this error?

Thanks a lot for any help,

Elemér.

You’ll need to create your own application on Okta for this to work. The client_id that’s in the GitHub repo refers to an application that I deleted. You can find the instructions in the blog post or the README.
