Refreshing an access token - PHP

[ralfonso4]

I stuck in the refresh token....
Getting:
#######
{"error":"server_error","error_description":"Internal server error","error_uri":"https://auth.tesla.com/error/reference/59671c5d-43ea-4226-863a-623ed95bdfc8-1612320397217"}
#######

protected $tokenUrlNew = 'https://auth.tesla.com/oauth2/v3/token';

public function refreshAccessToken(string $refreshToken)
{
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, $this->tokenUrlNew);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLOPT_TIMEOUT, 30);
curl_setopt($ch, CURLOPT_POST, true);
curl_setopt($ch, CURLOPT_HTTPHEADER, [
'Content-Type: application/json',
'Accept: application/json',
]);
curl_setopt($ch, CURLOPT_POSTFIELDS, json_encode([
'grant_type' => 'refresh_token',
'client_id' => 'ownerapi',
'client_secret' => getenv('TESLA_CLIENT_ID'),
'refresh_token' => $refreshToken,
'scope' => 'openid email offline_access',
]));

  $apiResult = curl_exec($ch);
  $apiResultJson = json_decode($apiResult, true);

  curl_close($ch);
  $this->accessToken = $apiResultJson['access_token'];

  return $apiResultJson;
}

Think i fixed it: Using the refresh_token from step3 and not from step4!!!

public function refreshAccessToken(string $refreshToken)
{
$tesla = new Tesla();
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, 'https://pastebin.com/raw/pS7Z6yyP');
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
$result = curl_exec($ch);
curl_close($ch);
$api = explode(PHP_EOL,$result);
$id=explode('=',$api[0]);
$secret=explode('=',$api[1]);
$tesla->setClientId(trim($id[1]));
$tesla->setClientSecret(trim($secret[1]));

  $ch = curl_init();
  curl_setopt($ch, CURLOPT_URL, $this->tokenUrlNew);
  curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
  curl_setopt($ch, CURLOPT_TIMEOUT, 30);
  curl_setopt($ch, CURLOPT_POST, true);
  curl_setopt($ch, CURLOPT_HTTPHEADER, [
    'Content-Type: application/json',
    'Accept: application/json',
    'User-Agent: Mozilla/5.0 (Linux; Android 9.0.0; VS985 4G Build/LRX21Y; wv) AppleWebKit/537.36 (KHTML, like Gecko) Version/4.0 Chrome/58.0.3029.83 Mobile Safari/537.36',
    'X-Tesla-User-Agent: TeslaApp/3.4.4-350/fad4a582e/android/9.0.0',
  ]);
  #print 'XX '.getenv('TESLA_CLIENT_ID');exit;
  curl_setopt($ch, CURLOPT_POSTFIELDS, json_encode([
    'grant_type' => 'refresh_token',
    'client_id' => 'ownerapi',
    'client_secret' => getenv('TESLA_CLIENT_SECRET'),
    'refresh_token' => $refreshToken,
    'scope' => 'openid email offline_access'
  ]));

  $apiResult = curl_exec($ch);
  $apiResultJson = json_decode($apiResult, true);

  curl_close($ch);
  #print_r($apiResult);exit;
  
  $apiResultJson = json_decode($apiResult, true);
  $BearerToken = $apiResultJson['access_token'];
  $RefreshToken = $apiResultJson['refresh_token'];

###Step 4: Exchange bearer token for access token

	$ch = curl_init();
  curl_setopt($ch, CURLOPT_URL, $this->tokenUrl);
  curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
  curl_setopt($ch, CURLOPT_TIMEOUT, 30);
  curl_setopt($ch, CURLOPT_POST, true);
  curl_setopt($ch, CURLOPT_HTTPHEADER, [
    'Authorization: Bearer '.$BearerToken,
    'Content-Type: application/json'
  ]);
  curl_setopt($ch, CURLOPT_POSTFIELDS, json_encode([
    'grant_type' => 'urn:ietf:params:oauth:grant-type:jwt-bearer',
    'client_id' => getenv('TESLA_CLIENT_ID'),
    'client_secret' => getenv('TESLA_CLIENT_SECRET'),
  ]));

  $apiResult = curl_exec($ch);
  curl_close($ch);
  
  $apiResultJson = json_decode($apiResult, true);
  $apiResultJson['refresh_token']=$RefreshToken;
  #print_r($apiResultJson);exit;
  $this->accessToken = $apiResultJson['access_token'];

    return $apiResultJson;
}
