使用AWS PHP SDK上传到AWS S3无法通过身份验证

I am using version 3.67.5 of AWS SDK PHP to upload files to S3. The code is in an Heroku dyno.

I've created the access keys, AWS_ACCESS_KEY_ID and AWS_SECRET_ACCESS_KEY, and set them as configuration variables in the Heroku instance. I know that they are there, because with getenv() I 've outputted them.

I'm using the following code:

try {
   //Create a S3Client
   $s3Client = new S3Client([
        'profile' => 'default',
        'region' => 'some-region',
        'version' => 'latest'
    $result = $s3Client->putObject([
        'Bucket'     => 'some-bucket',
        'Key'        => $fileName,
        'SourceFile' => $this->getParameter('photos_directory') . $fileName,
} catch (AwsException $e) {
    echo $e->getMessage() . "

Still, uploading a file, it shows the following error:

request.CRITICAL: Uncaught PHP Exception Aws\Exception\CredentialsException: "Cannot read credentials from /app/.aws/credentials"

I've tested passing a new element 'credentials' in the constructor, like they do in theirs unit tests, and the error is the same.

    The problem was in defining the profile as "default". When I removed the profile parameter, the error disappeared.

    When using the latest version, 3.67.8, the following error occurred:

    AWS HTTP error: Client error: `PUT https: // some-url` resulted in a` 403 Forbidden`

    Anyway, in my case, and in both versions, omitting the profile parameter was the solution.
