Regarding the validation error “Failed to generate JSON file,”
We suspect the issue is caused by the presence of special characters, particularly the apostrophe ('). This character should not appear in any fields such as item name, item description, customer name, customer address, company details, and similar entries.
Please review and remove any apostrophes from these fields, then attempt the validation again.
If the issue persists after this step, we recommend reinstalling your system to ensure all configurations are properly reset.
