POST request to github returns 500 error, what's the problem?

Question

PHP

Hello!
I request data to update the token from Github like this:

$data = $guzzleClient->post(
                    'https://github.com/login/oauth/access_token',
                    [
                        'form_params' => [
                            'refresh_token' => $user->github_refresh_token,
                            'grant_type' => 'refresh_token',
                            'client_id' => config('services.github.client_id'),
                            'client_secret' => config('services.github.client_secret'),
                        ]
                    ]
                );

On the local server everything works fine, but on the test server this error:

Server error: `POST https://github.com/login/oauth/access_token` resulted in a `500 Internal Server Error`

That is, the error is on the Github side.
What could be the problem?

It ended up being solved like this:

$guzzleClient = new \GuzzleHttp\Client([
                    'headers' => [
                        'Content-Type' => 'application/json'
                    ]
                ]);
                $data = $guzzleClient->post(
                    'https://github.com/login/oauth/access_token',
                    [
                        'json' => [
                            'refresh_token' => $user->github_refresh_token,
                            'grant_type' => 'refresh_token',
                            'client_id' => config('services.github.client_id'),
                            'client_secret' => config('services.github.client_secret'),
                        ],
                        'http_errors' => false
                    ]
                );

Guzzle has the ability to throw exceptions in case of errors - https://docs.guzzlephp.org/en/stable/quickstart.ht... - some types of exceptions have the ability to look at the server response. Wangyu that github in the answer writes in more detail what is wrong with your request.
