What are you trying to accomplish?

Preface: Related with JSON::ParserError issues.

Issue: Private registry usually returns 200 code in case of successful response. The response contains package information as a JSON object. But it was observed that some private registries return 200 code with an HTML markup (usually for login). throws a JSON::ParserError in case of invalid JSON object.

Fix: Identify if the response body being returned is valid JSON and raise proper exception in case invalid JSON.
