Variable 'object' does not exist

[ogurec-ogurec]

Hello, you made a great app, thanks for your work.

I had a couple of questions: an error,

1. installed demo everything works, but for some reason reactions are not pressed and a comment cannot be published. (I plan to use in the futureused PostresSQL).
2. For some reason, pages with a large number of comments open for a long time. Is it because the demo app is using db.sqlite3?
3. I also tried to put it on my project, it seems that I connected everything, but when I go to the page with comments, there is an error:

TemplateSyntaxError at /posts/test-posts
