I’m aware that this might not exactly be a Bokeh specific problem, but I’m wondering if anyone still has an idea to what is going on.
So my app deploys fine using two cdm terminals and 'bokeh serve random_generator.py --host="*"" and ‘python app.py’ my app shows up at 127.0.0.1:5006/random_generator.
However, although I send index.html into render_template() the header and paragraph text do not show up, only the actual random_generator shows.
I’m curious if anyone knows why this is? It’s probably some minor thing, but for the life of me I can’t find it
