Why is swagger validator failing here

Question

I can't seem to figure out why swagger validation is failing

What is strange is that if I add more than one path the validation only complains about the last one. Then if I remove the last one it starts complaining about the one above it.

When working in the swagger editor then it all seems to validate.

The swagger document is as follows:

while the validation error is as follows:

         }
      }
   ]
}

The required property of the parameters object should be a boolean type, not a string.

If you replace all "required":"true"s with "required":true and "required":"false"s with "required":false your example validates ok.
