Hello, I am kind of newbie in this so apologies if i ask something easy.
I am struggling to solve a problem similar to 351

I have JBrowse 1.15.1 with JBconnect running on an AWS instance.
I am using Google Chrome as browser.

My problem:
I have loaded my tracks (bam/bigwig etc)
I have tried also what is suggested here 1361
But no luck.

When i drag and drop to the combination track, even if it turns "green", nothing is loaded as track, however in the config of the combination track i see the key of my add track..

Interestingly i noted 2 things:

1. when I load 2 tracks, the dialog asks me for the function. I see this Javascript appear.
   

2. in the browser console, when i load a track i see these errors:
   

Is that an issue?
Do i do anything wrong.

Thank you very much.
A.
