I enfaced this error while vagrant up

Answer 1

I had this problem too. Instead of a wrong indentation, I accidentally added another dash ( - ) to my Homestead.yaml file.

For example, this is the incorrect one:

- map: testing.khc.my
- to: /home/vagrant/code/testing/public

The correct one is this:

- map: testing.khc.my
  to: /home/vagrant/code/testing/public

Hope this help everyone in the future.

Answer 2

I got this error too and it's a real pain. The source of the problem is a wrong indentation in the Homestead.yaml file. Check if you're using spaces or tabs.
