Connected flask-bootstrap to the project. I registered everything and did not change the contents of the base.html file which is located in the bootstrape. I run gives an error
werkzeug.routing.BuildError: Could not build url for endpoint '/static' with values ['filename']. Did you mean 'static' instead? then changed the inscriptions of bootstrap.static in the base.html file to static, but still gives an error at startup
{{ url_for('static', filename='css/normalize.css') }} url_for the first parameter is a folder and the second way can something wrong do?
