The expression return $curl could return the type resource which is incompatible with the type-hinted return CurlHandle. Consider adding an additional type-check to rule them out.

    /** @return HttpHeaders */

The type BEAR\Resource\HttpHeaders was not found. Maybe you did not declare it correctly or list all dependencies?

    private function parseResponseHeaders(string $responseHeaders): array
    {
        $responseHeadersArray = [];
        $headerLines = explode("\r\n", $responseHeaders);

            $responseHeadersArray[$key] = trim($parts[1]);
        }

        return $responseHeadersArray;

The expression return $responseHeadersArray returns the type array which is incompatible with the documented return type BEAR\Resource\HttpHeaders.

    }

    /** @return HttpBody */

The type BEAR\Resource\HttpBody was not found. Maybe you did not declare it correctly or list all dependencies?

    private function parseBody(CurlHandle $curl, string $view): array
    {
        $responseBody = [];
        $contentType = (string) curl_getinfo($curl, CURLINFO_CONTENT_TYPE);
        if (str_contains(strtolower($contentType), 'application/json')) {
            return (array) json_decode($view, true);

The expression return (array)json_decode($view, true) returns the type array which is incompatible with the documented return type BEAR\Resource\HttpBody.

        }

        return $responseBody;

The expression return $responseBody returns the type array which is incompatible with the documented return type BEAR\Resource\HttpBody.
