I am currently using arcGIS 4.19 version with react, typeScript. My code runs perfectly in my local dev environment however when I create a build and deploy it in an Azure appservice everything breaks. I recently switched to ES Modules from esri-loader. Previously it was working fine both in dev as well in Azure. I updated the Web server hosting configuration with proper mime type as mentioned in the documentation but still not working. Below is the error that I am getting in console
createForOfIteratorHelper.js:53 Uncaught TypeError: Cannot convert undefined or null to object

Note: I am parsing a JSON response and creating map points using projection in ArcGIS. Once the point graphics are created I am passing it to feature layer to generate the Map.
I am experiencing this exact issue, except on 4.22. Were you ever able to find a fix?
