CloudFrontKeyValueStore Signature v4a

[djoleeeee]

        $client = new Aws\CloudFrontKeyValueStore\CloudFrontKeyValueStoreClient(array(
            'region'  => 'us-east-1',
            'version' => 'latest',
            'credentials' => ['key'=> 'XXX', 'secret'=>'XXX'],
            'signature_version' => 'v4a'
        ));
        
        $list = $client->listKeys([
            'KvsARN' => 'arn:aws:cloudfront::XXX:key-value-store/XXX', // REQUIRED
        ]);

Error: This operation requests sigv4a auth schemes, but the client currently supports sigv4, none, bearer, sigv4-s3express.

Can someone help me with this?

Hi @djoleeeee, the service client CloudFrontKeyValueStoreClient requires the awscrt extension to be installed in order to work. Please follow the instruction found here to get it installed. Once you do this you should have not issue related to this. Please let me know if that helps.

Thanks!

Thank you so much!

I missed the PHP extension part (I just loaded the library with Composer).

Now it works.

This error occurs again after I upgraded my PHP version from 7.4 to 8.2.

Any ideas?

@yenfryherrerafeliz any news?

@djoleeeee I will get back to you soon.

Thanks!

Hi @djoleeeee,

I was unable to reproduce using PHP version 8.2. Is it possible your app is calling another instance of 8.2 somewhere else on your machine? It would be helpful if you could provide debug logs (add 'debug' => true to your client config). Just make sure to obscure any sensitive information, such as account numbers.

Suddenly, it worked after I downloaded the latest version of aws-sdk-php.

However, I don't think that's the reason. I suspect that I forgot to restart the server after the installation.

I'm sorry to bother you.

Thank you.

No bother at all— glad you were able to get it working!
