This is observed when apps are tested from local machine. Could that be the cause ?

No this is not the cause for transaction revert, but one of the reasons why gassless failed, it tried communicating with sepolia paymaster url but the cors for the url did not permit it, biconomy gassless work on Mumbai and polygon can the sender test on mumbai
