Esri Loader, Dojo.js injection problems, cannot read property 'insertBefore' of null errors

[KrzysztofMroczek]

In my Angular application I implemented map with Esri Loader. It is solution working on PRODUCTION SYSTEM.

I use Pusher.js for some communications. Randomly map does not show. I found that your dojo.js is trying to inject url to pusher script.. the screenshot for evidence. My question is how to workaround that problem. I guess dojo.js is wrong selecting script tag, for injecting your scripts to header tag.

Hi @KrzysztofMroczek , did you ever find a solution to this? This just started happening to us recently as well. Any thoughts are appreciated. JS API 4.28 and issue is recent and in Edge/Chrome, but not FF.
