Fatal error: Uncaught GuzzleHttp\Exception\RequestException: cURL error 60

[Raspberry42]

Hello Jerome!

I have an error when I do this:

<?php

// Test PHP - Firebase

require __DIR__.'/vendor/autoload.php';

use Kreait\Firebase\Factory;

$factory = (new Factory)->withServiceAccount(__DIR__.'/secret/test-ch82f-7cba9m5d4830.json');

$database = $factory->createDatabase();

$reference = $database->getReference('messages/w7jEw6jpRdRcBGLuWrWu');

$value = $reference->getValue('text');

echo $value;

Here is the error:

$ php index.php

I did what you say in the troubleshooting section (cURL error XX ...)

I did a var_dump (openssl_get_cert_locations ()); :

array (8) {
  ["default_cert_file"] =>
  string (42) "C: \ Program Files \ Common Files \ SSL / cert.pem"
  ["default_cert_file_env"] =>
  string (13) "SSL_CERT_FILE"
  ["default_cert_dir"] =>
  string (39) "C: \ Program Files \ Common Files \ SSL / certs"
  ["default_cert_dir_env"] =>
  string (12) "SSL_CERT_DIR"
  ["default_private_dir"] =>
  string (41) "C: \ Program Files \ Common Files \ SSL / private"
  ["default_default_cert_area"] =>
  string (33) "C: \ Program Files \ Common Files \ SSL"
  ["ini_cafile"] =>
  string (0) ""
  ["ini_capath"] =>
  string (0) ""
}

I downloaded the current CA bundle from https://curl.haxx.se/ca/cacert.pem

I renamed the cacert.pem file to cert.pem and pasted it in: C: \Program Files\Common Files\SSL

I configured the curl.cainfo parameter in the php.ini.

[curl]
curl.cainfo = /C:/Program Files/Common Files/SSL/cert.pem

I always get this error.
Could you help me please?
