When trying to preview my custom invoice template i get an error message saying
PDF.js v1.5.456 (build: 4d15928)
Message: stream must have data
Is the customer invoice template already imported and listed in your Custom Form Styles or are your previewing this on the import?
Can I also check the web browser you are currently using?
We would be grateful if you can attempt to import the invoice using a computer. We would also be grateful if you can provide us with a screen shot of the error you receive when you attempt the import using a computer.
It may be the document itself or the way you have mapped it being the reason you are not able to view a preview.
We would be grateful if you can PM us on FaceBook or DM us on Twitter with the email address associated with your QuickBooks account including your Community name Helen81.
There might be an error while mapping the fields, Eugene Sung.
Make sure to map your data by marking it with opening and closing angle brackets "<" and ">". Moreover, there might be brackets applied incorrectly. Try to check the fields with brackets until you're able to Preview successfully.
You also don't need to mark data that doesn't change such as your company name, address, and contact information.
