Answer 1

I came across this error

BuildError: ('project_admin', {}, None)

when I had a call like

return redirect(url_for('project_admin'))

in which I was trying to reference the project_admin function within my Blueprint. To resolve the error, I added a dot before the name of the function, like this:

return redirect(url_for('.project_admin'))

and voila, my problem was solved.
