I am using a barcode scanner, scandit 5.14.2 on Linux with a trial license. I am trying to run a python module sample i.e. CommandLineBarcodeScannerImageProcessingSample.py but I am getting the following error

Processing frame failed with code 15: The Scandit SDK license
  validation failed. Your app ID does not match the license key's app
  ID.

I have tried creating a new license key with Application ID / Bundle ID as the name of the file i.e. CommandLineBarcodeScannerImageProcessingSample.py but still getting the same error.
Same goes with CommandLineBarcodeScannerCameraSample.py but all c scripts run fine.
In FAQs of scandit it is mentioned that I should use program_invocation_name as bundle id. Is there something I am missing? Any suggestion would be very helpful
One does not need to create a new license ID for sample code from Scandit. One needs do the following:

login to your dashboard
go to the License Keys tab. There is a default license key already made. Use that.
