Build a Basic CRUD App with Angular 7.0 and Spring Boot 2.1
Angular and Spring Boot are arguably the two most popular frameworks in all of web development. Matt Raible shows you how to use them together in the same app, and how to secure it all with Okta.

Hi Mat, I cloned your git repository, changed your okta credentials to mine, then started up the applications. I am not getting a 500 error from your server. I turned off authentication and the endpoint works correctly. Any clue what might be wrong?
Matt Raible
Is there anything in your logs that indicate what the 500 error is caused by?
Alex Aldana
it says it is an invalid token.
Matt Raible
This usually happens when you have an invalid issuer (make sure you’re using something like https://dev-123456.oktapreview.com/oauth2/default), or your client IDs don’t match. Make sure your client and server are using the same settings.

Hi, Matt.
Thanks for this great work. I am having problems trying to run the client code after cloning the code.
It’s a problem with typescript versioning. Please see error below:
I have been trying to resolve this in the last 8 hours without any luck. Google is not helping:
ERROR in The Angular Compiler requires TypeScript >=3.0.1 and <3.1.0 but 2.9.2 was found instead.
Sydney
Oh never mind, Matt. I’ve figured it out finally 
. I had to run this command sudo npm install typescript@">=3.0.1 <3.1.0" to force it to pick any version of typescript available between 3.0.1 and 3.1.0 and it picked 3.0.3, which is good enough to be greater than the required 3.0.1.

hi Matt, thanks for this awesome tutorial app you build. I have a small issue when trying to deploy it to heroku. Sorry I’m still a newbie with Angular and Springboot. I appreciate your help.

Matt Raible
What’s the error you’re seeing on Heroku? I can’t help solve the problem if I don’t know what it is.

This is the error that I received after my attempt to deploy

That’s expected for the server. The blog post has this same screenshot.

Your reminder that angular 7 is out.
Matt Raible
Thanks Chuck! I’ve added this blog post to my list of ones to update this week.

Are you sure you have an Okta developer account and not an Okta IT account? If you do, you might try cloning this blog posts example project, changing the settings to match your Okta tenant (instructions are in the project’s README), then running it.
