Error when publish

[David_Gosser]

I uploaded the "minimal bookdown document" files from github, and builds on rstudio cloud,
and the bookdown document appears. however when i try to publish using rstudio connect, to bookdown, i get errors:

1. error seems to be about bs4 but i am publishng gitbook. i assed suggested packages but still get the same error.

sometimes it publishes, but the chapters give 404 error when linked.
