Error: Worker was destroyed about vue-pdf HOT 9 CLOSED

I have to investigate the issue further. PDFJS.disableWorker = true should be considered as a workaround.

from vue-pdf.

That little fix solve the problem for me.
mozilla/pdf.js#8738
hope it will merge soon

If it not accepted there we can change this to the end of "loadDocument" in pdf.vue

loadingTask
.then(function(pdf) {
	pdfDoc = pdf;
	emitEvent('numPages', pdf.numPages);
	emitEvent('loaded');
})
.catch(function(err) {
	clearCanvas();
	clearAnnotations();
	emitEvent('error', err);
})
.then(function(){
	loadingTask._worker = null;
})

@ChenMachluf thanks for your fix !
Since several people are waiting for this fix, I commit your 2nd proposition while mozilla/pdf.js#8738 is pending.

Solved by setting
PDFJS.disableWorker = true

from vue-pdf.

@FranckFreiburger one alternative might be to explicitly set the worker in the created hook.

Something like PDFJS.workerSrc = 'pdfjs/build/pdf.worker.js'

from vue-pdf.

Where would the PDFJS.disableWorker = true go into effect?

from vue-pdf.

where set the PDFJS.disableWorker = true , i tried in the created () lift-time ,i see the PDFJS.disableWorker is
true ,but the error still exist

Hi,
Tried both PDFJS.disableWorker=true and setting PDFJS.workerSrc without success.
Any other suggestions?

Thanks!

Hi, same problem here.
The only solution that worked for me was to set the doc src to null value just after calling the print() method.

Html:
<pdf ref="invoice" :src="pdf_src"></pdf>

JS:
this.$refs.invoice.print()
setTimeout(() => { this.pdf_src = null }, 500)

By doing that, the destroy method will never be called (https://github.com/FranckFreiburger/vue-pdf/blob/master/src/pdf.vue#L178)

It's just a workaround
