Issue with Javascript loading with slow internet connection

I seem to be having an issue with what I believe to be the core javascript files (not my own, but those phpmaker is trying to use) from loadjs not loading either in the correct order or at the correct time. I’m using PHPmaker 2023.10. When a customer has a slow internet connection, everything appears to go haywire. They can’t click any buttons, edit, etc.

Looking at the browser console window, I consistently see 2 javascript errors (again, only when using a slow internet connection). Those two errors are:Uncaught TypeError: Cannot read properties of undefined (reading ‘amd’) ew.min.js?v=19.10.0.0:5andUncaught TypeError: ew.FormBuilder is not a constructor CalendarEventsList:269 (but this can be whatever page they are on, not just the List pages).I know the javascript files are loaded by loadjs, so I’m unsure if something isn’t loading in time or in the correct order. To duplicate this issue, I can fire up chrome, go to the network tab and change the connection to “slow 3g”. It will give the error anytime I try to load the page.If I go to my normal internet connection, everything loads just fine. For my customer, it is intermittent, so I’m assuming it depends on their connection speed at that moment of page loading.Does anyone have any ideas about what might be the problem?

The first error is probably due to missing select2.full.min.js, make sure you have jquery/select2.full.min.js, do not try to add select2 yourself.The second error is due to the first JavaScript error so ew.min.js cannot be loaded successfully.

I can confirm select2.full.min.js?v=19.10.1 is being loaded through the network inspector. I’m just worried that it is not loading at the correct time? And remember, this only occurs with slower internet connections. Faster connections the page loads fine.

I have tried “Slow 3G” throttling in Chrome a dozen times but still cannot reproduce.
