I updated to @arcgis/core to 4.19.0 from @4.18.1, it installed and compiled successfully. However when trying to view map in the browser, I got a bunch of errors regarding Promise.allSettled
I am using Angular 8.2.14 and Node version 10.18.1
Solved! Go to Solution.
What browser version are you using? Promise.allSettled is not supported in older browsers.
Edited as I noticed your screenshot is Chromium dev tools. Might need to update the browser.
