This code seems to be duplicated across your project.

                $message = 'JSON file (' . (string) $response->getUri() . ')  does not validate against the following JSON Schema files: ' . implode(', ', $messageParts);

It seems like you code against a concrete implementation and not the interface Psr\Http\Message\ResponseInterface as the method getUri() does only exist in the following implementations of said interface: phm\HttpWebdriverClient\Http\Client\Chrome\ChromeResponse, phm\HttpWebdriverClient\Http\Client\Guzzle\GuzzleResponse, phm\HttpWebdriverClient\Http\Client\Guzzle\Response, phm\HttpWebdriverClient\Http\Response\BrowserResponse, whm\Smoke\Http\ConnectionRefusedResponse, whm\Smoke\Http\ErrorResponse.

                throw new ValidationFailedException($message);
            }
        }
    }
