Null Pointer error while trying to parse the UUID of the device during bluetooth Advertisement

I am making an app for conducting Bluetooth experiments but whenever I click on the button that starts the Bluetooth transmission using an Advertiser the app just returns to the home screen and gives an error

The error comes only when I add the lines .addServiceUuid( pUuid ).addServiceData( pUuid, "Data".getBytes( StandardCharsets.UTF_8 ) ) in the following block of code :

ParcelUuid pUuid = new ParcelUuid( UUID.fromString( getString( R.string.ble_uuid ) ) );
        AdvertiseData data = new AdvertiseData.Builder()
                .setIncludeDeviceName(true)
                .addServiceUuid( pUuid )
               .addServiceData(pUuid,"Data".getBytes(StandardCharsets.UTF_8))
                .build();

There is no error on building the app, the error occurs only when I click the button that starts the Bluetooth Advertisement.
