Recently, when I was working on a project based on Spring boot, I changed the application.yml, which caused the IDEA to start with an error:

Java.lang.IllegalStateException: Failed to load property source from location 'classpath:/application.yml

So there are three reasons for finding all kinds of solutions online:

The contents of the application.yml file are not indented in the correct format.

The comment on the yml file is "#", not "/ /".

The application.yml file code is inconsistent with the project code.
