Issue: Error Creating UUID for ETX Receipt
Problem Statement:Despite following all the instructions provided by the source for generating a UUID for an ETX receipt, errors persist during the process.
Source Instructions Followed:The UUID generation steps were taken from the official guidelines available at:ETA Receipt Issuance FAQ – UUID Generation
Steps Taken:
Implemented the UUID generation logic as per the provided documentation.
Ensured all required parameters were correctly formatted and included.
Verified system date, time, and unique transaction identifiers.
Checked for any potential conflicts or duplicate values.
Attempted multiple runs with different test cases.
Encountered Errors:
Error messages related to UUID creation.
Request for Assistance:Seeking guidance on:
Debugging methods for UUID generation errors.
Confirming the correct implementation of the required format.
Understanding any additional requirements not explicitly mentioned in the documentation.
Any insights or solutions from those who have successfully generated UUIDs for ETX receipts would be greatly appreciated.
