another program can read it just fine, e.g.

I don't know why it doesn't work for you yet...

I see @luochen1990 . I have a different node version

$ node --version
v14.16.0
$ npm --version
6.14.11

[luochen1990]

That is weird, from your stacktrace info, it seems that there is no Pages attribute here, and this seems impossible to be a nodejs version compatibility issue... hmmm

@luochen1990 I'm running into similar problem, seems to be after pdf2json dependency minor version update to above 1.2.3 (1.3.1atm).

I believe it's connected with https://github.com/modesty/pdf2json/issues/249#issuecomment-953029255

data structure

//before
pdfData.formImage.Pages
//after
pdfData.Pages

biggest issue is that certain small svg elements aren't visible anymore in Fills Array for Pages Object. Those were present with version 0.0.4.

//edit

I've been also testing different pdf2json versions with node v14.16.0 and v16.14.2. Few observations:

pdf2json v1.2.1 - v1.2.4:

• node v14.16.0, working with formImage.Pages structure
• node 16.14.2, silenty closing -> not parsing

pdf2json v1.3.1 and v2.0.1:

• works with both node versions but structure is lacking formImage
