Trying to run Spring Boot and React together but server is returning 404 when trying to provide reso-CodePudding

I've been following

When I then have a look intellij's console, I get the following error:

As you can see, it doesn't seem to find the files at all. However, they're definitely there:

This is what my applications.properties file looks like so far:

I'm not sure what is causing this to happen as it all looks correct... However, I must be missing something otherwise this wouldn't be happening.

EDIT:

Here is my Github repository which has the whole project on it.

Please refer this project to get your answer https://github.com/vinodhmahendra/simplilearn-phase3-2022/tree/master/14-todo-service-rest-jpa-h2 First of all your springboot project is exited with error.Make it run and if that started working with postman same url you have to pass to your react application.IF you are taking url through env variable make sure it starts with REACT_APP.
