Custom component not working when switching to on premise

[nevvo]

Hello there,

I have a custom control that I have developed that when I am hooking it up to point at the online ArcGIS JavaScript source (https://js.arcgis.com/4.25) it works as expected when I provide it a valid portal and portal id.

We also have an internal portal server running 10.9.1 and we are serving up the equivalent 4.25 JavaScript using the scripts downloaded from here (https://developers.arcgis.com/downloads/#javascript) - I didn't configure this but it is definitely serving up the contents.

If I then take that exact same component and try to use our internal setup it is exhibiting different behaviour. I am getting the following errors in the browser console when the control is trying to load the map:

init.js:29

t @ init.js:6

My control makes no specific calls to any behaviour in the (decorators | API Reference | ArcGIS Maps SDK for JavaScript 4.26 | ArcGIS Developers) - UPDATE - after tracing through a bit further it looks as though it is the Point class that uses this (I need to use Point).

I am not sure as to why it works online but not on prem.

Does anyone have any idea as to what might be happening here?

Thanks,

Hi @nevvo, thanks for posting your question here. I looked at the downloaded 4.25 init.js, and it looks like ./core/accessorSupport/decorators/cast should be included. Is there a simplified repro app you can share for testing? Can you try running the app with 4.26? And also downloading 4.26 and testing with that to see if it works?

Hi there,

Thanks for the reply.

After a bit more investigation it turns out someone had manually edited the init.js file and had mistakenly pasted in https://test.maps.my-domain.com/javascript/api/4.25/init.js to the file which was causing the problem.

Thanks
