TypeError: this.extension.manifest.calendar_item_details is undefined [non blocking]

[LouisJULIEN]

Hello,

Here is an error I encountered while developing my Thunderbird plugin that uses the calendar experiment.

I've been having an error message each time I opened an event in my calendar. The error message appears in the developer console. It is invisible to a "normal" user and non blocking (even for a dev).

I think it's not related to my plugin code, though I didn't double check with a blank plugin that uses only the calendar experiment with no extra code.

Here is the full error message and a video to show the error
