Uncaught Exception: Unable to load private key

[Tekrajs]

I tried your sdk for wall-mart integration but it failed at the very beginning. I did the dollowing thing:

        require_once 'vendor/autoload.php';
        
        use Walmart\Feed;
        
        $client = new Feed([
            'consumerId' => 'MYCONSUMERKEY',
            'privateKey' => 'MYPRIVATEKEY'
        ]);
        
        $feed = $client->get([
            'feedId' => 'EAA473B65DFF4DA6A80DA4C8586E4BA9@AQMBAQA', // required
            'includeDetails' => 'true', // optional, default false
            'limit' => 50, // optional, default 50
            'offset' => 0, // optional, default 0
        ]);

But vendor/fillup/walmart-auth-signature-php/src/Signature.php:112 here error is thrown.
I checked there

    if($rsa->loadKey($decodedPrivateKey,RSA::PRIVATE_FORMAT_PKCS8)){}

was checked. Which then returned false. So I went to $rsa->loadKey where I saw

    if ($key instanceof RSA) {}
    if ($type === false) {}else {
        $components = $this->_parseKey($key, $type);
    }

The code enters into else statement where _parseKey returns false. What is actually happening here ? Am I missing any php modules or is this the fault of SDK ?

Please help me out on this. Thanks
