Hi,
Since 4.20 we are having issues printing with our own Print Service, via the Print widget. We're getting an error when hovering over the exported files section "An error occured while exporting the webmap.".
I have tested the widget with the ESRI Print Service and it does work. The only difference I can see, is our service is asynchronous.
I assume this is linked to the changes related to the rest modules?
edit: More info
stack error: "TypeError: Cannot destructure property 'returnFeatureCollection' of 's' as it is null. at p.fetchResultData (http://localhost:8080/js/33.js:211:1559) at o (http://localhost:8080/js/46.js:39:926) at async print (http://localhost:8080/js/84.js:156:1933)"
ps: we changed our service to synchronous, and it works again. (but we'd like a fix for the async method...)
