Uncaught (in promise) TypeError: Cannot read property 'styles' of undefined

[brandondb1]

Hello,

I am getting this error in the browser console (at line 30 and a bunch at line 1 of template-entity-row.js), while getting "Custom element doesn't exist: template-entity-row." in the UI.

It works if I set it up manually, but doing it from code with:

add_extra_js_url(hass, "/local/template-entity-row.js")

creates the issue (regardless of the subfolder I use). This method works fine with other cards, including auto-entities.

I'm trying to write an integration that packages some things together, hence the code approach...

I understand this is perhaps an issue of my own creation, but thought I'd ask to see if anything stood out to you.

Thanks again!

exact browser log:

Did you figure out this one? I am hitting the same error when adding this module manually using

frontend:
  extra_module_url:
    - /local/template-entity-row.js
