Screenshot of Swagger Editor & code Hi, I am new to API testing and Swagger and am getting this parser error message in the Swagger Editor and I am having problems locating the problem.

Bellow is a copy paste of the code.

The error message is "bad indentation of a mapping entry" and is displayed where --> in: "path".

I followed this YouTube Tutorial --> https://www.youtube.com/watch?v=CoUl9_NWdqQ

Solution

Change

type: "String"

type: "string"

Note the lowercase "s" in "string".

All OpenAPI type values are lowercase and case-sensitive.

Also, make sure there are spaces after - in parameter definitions (and in YAML lists in general), and that the indentation is correct:

- name: "id"
  in: "path"
  ...
