i am using prince for some time.
i use nodejs
prince stopped working ad i didnt made any changes.

this is my code:

const Prince = require("prince")
const util = require("util")

const timeStamp = +new Date();

Prince()
.inputs("1679928942030.html")
.output(`${timeStamp}.pdf`)
.execute()
.then(function () {
console.log("OK: done")
}, function (error) {
console.log("ERROR: ", util.inspect(error))
})

this is the error:

{

Does the input file exist? And is the filename 1679928942030.html or 679928942030.html?

the file exists and its name is 1679928942030.html

It looks as if there's a problem in one of the javascript files that's calling prince: notice that some of the error messages say "167...html" while some say "67...html". Following the chain of error handlers should give a clue as to where the corruption is occurring.

The bytes in the value for stderr above (where it says "stderr: <Buffer 70 72 69 ...") correspond to "prince: 679928942030.html: error: can't open input", i.e. without the 1; whereas all following error messages include the 1.

[Where "following" means following in the combined error message as included in the original forum message, rather than following error as ordered by time of occurrence at runtime.]

The .js source file names appearing in the error message might also give a clue as to where the problem is occuring. You might be able to add a console.log() call giving the HTML filename as seen by each place in the stack trace.
