DOMException: Failed to execute 'importScripts' on 'WorkerGlobalScope': The script at 'http://localhost:4200/BlinkCardWasmSDK.js' failed to load

I am trying to get this credit card reader to work on my angular application. I followed all the steps in the read me and got a license key as well but for some reason I am getting the following error

Error during the initialization of the SDK! DOMException: Failed to execute 'importScripts' on 'WorkerGlobalScope': The script at 'http://localhost:4200/BlinkCardWasmSDK.js' failed to load.

in my component I have the following method implemented from the instructions:

 scanCard() {
    if ( BlinkCardSDK.isBrowserSupported() ) {
      const loadSettings = new BlinkCardSDK.WasmSDKLoadSettings( 'sRwAAAYJbG9jYWxob3NjpmqGCINgvA==' );

      BlinkCardSDK.loadWasmModule( loadSettings ).then
      (
        ( wasmSDK: BlinkCardSDK.WasmSDK ) => {
          // The SDK was initialized successfully, save the wasmSDK for future use
          BlinkCardSDK.createBlinkCardRecognizer( wasmSDK ).then(recognizer => {
            BlinkCardSDK.createRecognizerRunner( wasmSDK, [ recognizer ], true ).then(recognizerRunner => {
              const cameraFeed = document.getElementById( 'myCameraVideoElement' ) as HTMLVideoElement;
              BlinkIDSDK.VideoRecognizer.createVideoRecognizerFromCameraStream(cameraFeed, recognizerRunner)
                .then(videoRecognizer => {
                  videoRecognizer.recognize().then(processResult => {
                    if ( processResult !== BlinkIDSDK.RecognizerResultState.Empty ) {
                     recognizer.getResult().then(recognitionResult => {
                       console.log( recognitionResult );

                     });
                    } else {
                      console.log( 'Recognition was not successful!' );
                    }
                    console.log(processResult);
                  });

              });
            });

          });
        },
        ( error: any ) => {
          // Error happened during the initialization of the SDK
          console.log( 'Error during the initialization of the SDK!', error );
        });
    } else {
      console.log( 'This browser is not supported by the SDK!' );
    }
  }

in the html I have:

<video id="videoElement">

I have added the BlinkCardWasmSDK.js in the /src/assets/BlinkCardWasmSDK.js but it still gives me the error. Am I missing a reference or something? Thanks in advance for the help.

In the browser I get the following error zone-evergreen.js:171 Uncaught Error: Unknown message action: undefined at context.onmessage (BlinkCardWasmSDK.worker.min.js:15) at wrapFn (zone-evergreen.js:1218) at ZoneDelegate.invokeTask (zone-evergreen.js:399) at Zone.runTask (zone-evergreen.js:167) at ZoneTask.invokeTask [as invoke] (zone-evergreen.js:480) at invokeTask (zone-evergreen.js:1621) at globalZoneAwareCallback (zone-evergreen.js:1647)
