Estou tomando esse erro. O que pode ser ? Warning: curl_setopt_array(): Cannot represent a stream of type Output as a STDIO FILE in C:\xampp\htdocs\Logos CRM\vendor\guzzlehttp\guzzle\src\Handler\CurlFactory.php on line 70
cURL error 0: The cURL request was retried 3 times and did not succeed. The most likely reason for the failure is that cURL was unable to rewind the body of the request and subsequent retries resulted in the same error. Turn on the debug option to see what went wrong. See https://bugs.php.net/bug.php?id=47204 for more information. (see https://curl.haxx.se/libcurl/c/libcurl-errors.html) for https://pix-h.api.efipay.com.br/oauth/token
