Jinja2 import is borken about flight_review

[bkueng]

What is the exact exception?
I don't get an error with 3.1.1.

Apologies, it seems to be a combination between the Bokeh and Jinja2 version. So templates.py in bokey lib, so not stricktly speaking a PX4/flight_review problem.

Packages in my venv:

bokeh==2.1.1
Jinja2==3.1.1

I'm facing the same problem, it seems like by upgrading the bokeh==2.1.1 to bokeh==2.4.2(latest) can be fix this error.
But need to test first.

[luvwinnie]

I have tested that if upgrade from bokeh 2.1.1 to 2.4.2 would broke the program, instead make sure that Jinja2 use for example 3.0.0 instead of latest 3.1.1.

Should be resolved with #238
