Upgrading to Arcgis 4.12 throws an error: ERROR TypeError: Cannot read property '1' of undefined

[dlokman]

We use Arcgis for javascript 4.11 and after loading the map on the UI, everything works fine. However, we just upgraded to use version 4.12 and we are getting the following error on page load. Can someone please help us resolve this? Thanks

this isn't the best spot to be asking for help with the ArcGIS API for JavaScript.

you should either log a technical support ticket or use GeoNet.

ok thanks for letting me know

[jgravois]

no worries. if you haven't already I'd also recommend checking out the "breaking changes" section of the 4.12 release notes.

Yeah Thanks. Unfortunately the Release Notes don't help. I'll try GeoNet and submitting a support ticket. Thanks for your help
