Component from a custom module not being rendered in chat

[VoloKozak]

Describe the bug
I created a custom module with a skill and a custom time component based on the existing date-picker examples repository. When I build and run my local botpress server - everything happens without errors. But when it comes to calling the custom component - it is not rendered in the chat. Action send-date-picker being called, but nothing is actually rendered (see the screenshot below).
I can't figure out why, because I've made a similar custom module before and everything was fine.

I'm using this v12 repo and running it locally. Custom module was created according to all instructions here

P.S. This issue may be linked to lates changes in botpress v12, cause it's working fine on previous versions, but when we upload it to the newest one - we experience that.
