mapping values are not allowed here in "<unicode string>"

I am using yml properties for spring boot app. I am getting error on yml as below:

onboarding: 
  api: 
    something: 
      attribute1: 
      attribute2:
    somethingElse: 
      atribute: 
    base-url: http://enpoint.elasticbeanstalk.com
      users: /users ## error here on colon symbol
        save-update: /users/save-update

My usage is as below:

@Value("${onboarding.api.base-url.users}")
@Value("${onboarding.api.base-url.users.save-update}")

What am I doing wrong? Getting same error on any online parser too.

In YAML, every key has one value. A scalar is a value. A nested mapping is also a value. Apparently, you try to give the key base-url two values, the first one being an URL (which is a scalar) and the second one being a mapping containing a key users. That won't work.

So YAML parses http://enpoint.elasticbeanstalk.com and sees „okay, this key contains a scalar value“ and then on the next line, you start a nested mapping. This is what the error message is trying to tell you.

This would be valid YAML:

onboarding: 
  api: 
    something: 
      attribute1: 
      attribute2:
    somethingElse: 
      atribute: 
    base-url: http://enpoint.elasticbeanstalk.com
    users: /users
    save-update: /users/save-update

so would this:

onboarding: 
  api: 
    something: 
      attribute1: 
      attribute2:
    somethingElse: 
      atribute: 
    base:
      url: http://enpoint.elasticbeanstalk.com
      users:
        path: /users
        save-update: /users/save-update
