Minified version of pdf worker doesn't send correct exception

[Wykks]

Configuration:

• Web browser and its version: Chrome
• Operating system and its version: Windows 10
• PDF.js version: 2.5.207
• Is a browser extension: No

Steps to reproduce the problem:

Just use any not pdf file to trigger a InvalidPdfException

getDocument().promise.catch((error) => console.log(error);
error is undefined when using the minified version of the pdf worker (the one inside pdfjs-dist/build/pdf.worker.min.js).

What is the expected behavior?

The error should be InvalidPDFException {message: "Invalid PDF structure.", name: "InvalidPDFException"} even when using the minified version of the pdf worker.

What went wrong?

Using pdf.worker.es5.js (should be fine with pdf.worker.js too):

Using pdf.worker.min.js:

And here:

pdf.js/src/display/api.js

Lines 2332 to 2350 in 6e55326

	messageHandler.on("DocException", function (ex) {
	let reason;
	switch (ex.name) {
	case "PasswordException":
	reason = new PasswordException(ex.message, ex.code);
	break;
	case "InvalidPDFException":
	reason = new InvalidPDFException(ex.message);
	break;
	case "MissingPDFException":
	reason = new MissingPDFException(ex.message);
	break;
	case "UnexpectedResponseException":
	reason = new UnexpectedResponseException(ex.message, ex.status);
	break;
	case "UnknownErrorException":
	reason = new UnknownErrorException(ex.message, ex.details);
	break;
	}

reason is not going to be defined when name === 'e'
