Expected block end YAML error

This error also occurs if you use four-space instead of two-space indentation.

e.g., the following would throw the error:

fields:
    - metadata: {}
        name: colName
        nullable: true

whereas changing indentation to two-spaces would fix it:

fields:
  - metadata: {}
    name: colName
    nullable: true

The line starting ALREADYEXISTS uses ’ as the closing quote, it should be using '. The open quote on the next line (where the error is reported) is seen as the closing quote, and this mix up is causing the error.
