[tangximing]

Description

I'm trying to read form from pdf with code below, but ends up with error like this "field partial name (T) not specified"

ReadForm(arg *ReadFormArg) (resp string, err error) {
	fd, err := fjson.LoadFromPDFFile(arg.Filename)
	if err != nil {
		return
	}
	if fd == nil {
		return
	}
	resp, err = fd.JSON()
	if err != nil {
		return
	}
	return
}

Expected Behavior

parse the pdf successfully and return form json string

Attachments

there are two form fields in pdf attachment, and the second one is just copied from the first one. if I replace the second one with created form field not copied, it's ok.

@tangximing We cannot reproduce this. Can you test this again with newest unipdf and provide a self-contained example with full code and files so that it can be reproduced.
