`Response is not valid json content` when RDAP returns an error

[klkvsk]

When RDAP server returns a protocol error, such as:

{
  "errorCode": 429,
  "title": "Error in processing request",
  "description": [
    "Server is busy now, please try again later.",
    "Too Many Requests"
  ],
  "lang": "en"
}

it results in

InvalidDataTypeException: Response is not valid json content

client fails to assert that due to

RDAP-Client/src/Response/Abstracts/AbstractResponse.php

Lines 77 to 80 in d1d4f8f

	if (!is_array($responseJson) || !is_string($responseJson['objectClassName']??null)) {
	throw new InvalidDataTypeException(
	'Response is not valid json content'
	);

objectClassName is not in the response data.
Better to check for rdapConformance that always is in the response of any kind.

But actually best would be to throw a response exception with received code and description.

Thank you @klkvsk for reporting the bugs. Sadly, I am no longer focusing on this project. If you can, please feel free to submit a pull request or contribute to the fixes. I’d really appreciate the help!

That was my fault! cause not clearly recording any response from rdap if contain Error API.

Maybe adding RdapErrorResponseException and store the Data / Object data it should be good!
