@AshishH , 

If your project was exported from your PDI , and imported into the customer instance, then there is a chance of some core records ,like page templates  / related dependencies didnot import correctly.

• Check for missing or mismatched records by running the following:

  • Open your workspace record in the customer instance.

  •  verify all linked records exist.

• Look for errors in System Logs > All or UI Builder > Network tab (in browser Dev Tools) when attempting to create the page

• Confirm both PDI and Your Customer instance are in Same version ( PDI might be on different Service Now Version / plugin Configuration than Customer instance ) 
• Network Debugging for 400 Bad request ( Dev Tools -> Network Tab )

@New Developer_S It is not working even if i create a new experience in customer instance. 

Not sure if the customer instance is missing with some setting/configuration.
