Unable to deploy Server error 500

@okware_256, all you need to do is follow the steps outlined below:

  • Open online validator.
  • This screen appears as shared below:
  • There press Choose File and upload your XLSForm.
  • Once the XLSForm is uploaded there, press Submit.
  • As soon as you press Submit, you will see something as shown below:
  • Now press Preview in browser. If your XLSForm has issues, you will see errors and will not be able to open your XLSForm in a browser. But if your XLSForm doesn’t have issues, you will be able to load your XLSForm in a new browser.
  • If you see errors, you will need to go back to your XLSForm and fix the issue, save your XLSForm, and then go back and re-upload your XLSForm to validate your XLSForm again. You will need to repeat this cycle until you resolve your issue.
