View function mapping is overwriting an existing endpoint function: index

[rarevesselt]

sorry, at the moment I can not offer advise, structure looks fine and in accordance with the recommendation
I haven't use flask_script and frankly for what you use it here I would simply use separate script, without link/import of app that seems to cause the problem.
As a side note - maybe it's better to migrate to new Flask CLI

Thanks so much.I will work on this and let you know how it turns out.
