I am having a problem my Jupyter widget and I believe it is a 3.x to 4.x migration problem. I’ve been struggling with this and would it if I could get some help.
At the present state, installing my dev package prevents Jupyter running. In a clean environment, when I try to start Jupyter Lab I get a blank page and this appears in the console:
TypeError: can't convert undefined to object .excmds_content.generated.ts:2097:27
Uncaught (in promise) TypeError: t is undefined

When I uninstall my dev package, Jupyter Lab works fine. There’s something wrong with my JavaScript Extension code. My code has no variable named t though.
You can find the code I am using here:
It is build with these commands:
jlpm install
jlpm build
hatch clean
hatch build
I did the best I could with the Extension Migration Guide and worked through a lot of issues already but am stumped by this one.
You can see the packages installed in my environment here:
I’m happy to try the migration again, or anything else to get this to work correctly. Thanks!!!
