Uncaught (in promise) cancelled

Seems if I destroy a worker after scheduling a render task, something in rendering promise triggers a cancelled error which I can’t catch. (I’ve tried to intercept render(...).promise.catch, so I get cancelled, but error still occurs).

I see that when using your document, but it’s expected. The render promise must be resolved to something (and it shall not be a success)

To avoid breaking in the debugger tools or console message, please use catch e.g.:

       page.render({
          canvasContext: canvas.getContext('2d'),
          viewport: page.getViewport(scale),
        }).promise.then(function() {
          console.log('finished');
        }, function (reason) {
          console.log('stopped ' + reason);
        });

or

       page.render({
          canvasContext: canvas.getContext('2d'),
          viewport: page.getViewport(scale),
        }).promise.catch(function (reason) {
          console.log('stopped ' + reason);
        });

I hope this helps.
