DRM Playback in safari : Error Code: MEDIA_ERR_DECODE

[alenzalex]

Safari Version : 13.1

When I play DRM content in safari, I get error as
KeySession error: code 6, systemCode 4294924646
with error code as : (CODE:5 MEDIA_ERR_ENCRYPTED)

Then, it displays error as
The media playback was aborted due to a corruption problem or because the media used features your browser did not support
with error code : (CODE:3 MEDIA_ERR_DECODE)

getCertificate() -----> executed and return success
getContentId() -----> executed and return success
getLicense() -----> never enters this function

Attaching code snippet that I have tried :

player.ready(function () {
player.eme();
var emeOptions = {}

player.src({
    src: videSourceUrl,
    type: 'application/x-mpegURL',
    keySystems: {
	     'com.apple.fps.1_0': {
  	      getCertificate: function(emeOptions, callback) {
    		   let reqBody = { merchantId: 'myapp_testing' };
                   videojs.xhr({
                      uri: 'http://localhost:3080/getCertificate',
                      method: 'POST',
                      responseType: 'arraybuffer',
                      body: JSON.stringify(reqBody),
                  headers: {
              	     'Content-type': 'application/json'
                   }
          	}, function (err, response, responseBody) {
            	if (err) {
                console.log('error in getCertificate')
              		callback(err);
              		return;
            	}
              console.log('success in getting Certificate')
              callback(null, responseBody);
            	//var lab = decodeB64ToUint8Array(responseBody.license);
            	//callback(null, lab);
          	});
  		},

  		getContentId: function(emeOptions, initData) {
    	          console.log('Fairplay: getContentId')
                      const hostname = getHostnameFromUri(Utf8ArrayToStr(initData))
                      console.log('Fairplay: getContentId acquired')
                      return hostname
  		},

  		getLicense: function(emeOptions, contentId, keyMessage, callback) {
                    console.log('Inside getLicense:to proxy')
                    let reqBody = {
                            accountId: 'accountId',
                            videoId: 'videoId',
                            merchantId: 'myapp_testing'
                         };
                 var spcMessage = encodeURIComponent(encodeToB64Uint8Array(keyMessage));
                 var keySystem = emeOptions.keySystems['com.apple.fps.1_0'];
                 var options = keySystem.vendor.options;
    	     videojs.xhr({
            	       uri: 'http://localhost:3080/getLicense',
            	       method: 'POST',
            	       responseType: 'text',
            	       body: "spc=" + spcMessage + "&" + contentId,
            	       headers: {
              	          'x-dt-auth-token': options.authToken,
                              'x-dt-custom-data': normalizeCustomData(options),
                              'Content-type': 'application/x-www-form-urlencoded' 
                   }
          	}, function (err, response, responseBody) {
            	if (err) {
              		callback(err);
              		return;
            	} else {
            		callback(null, new Uint8Array(responseBody));
            	}
          	});
  			}
		}
	}
  });
});
