Handling of HTTP error messages

[aSauerwein]

Some failed request do not return any body element resulting in a unclear error message

For example an API Request to an intersight instance with self signed certs results return a {"changed": false, "msg": "API error: 'body' "}

A request to a non existent domain "bogus.intersight.com" also returns a:
{"changed": false, "msg": "API error: 'body' "}

The problematic code is at intersight.py 186ff

        try:
            response, info = self.intersight_call(**options)
            if not re.match(r'2..', str(info['status'])):
                raise RuntimeError(info['status'], info['msg'], info['body'])
        except Exception as e:
            self.module.fail_json(msg="API error: %s " % str(e))

Those 2 Errors do not return a "body" value => resulting in a KeyError.

A possible fix would be to exclude the "info['body']" from the RuntimeError statement or use info.get('body', '') instead.
