I am trying to deploy a small Dash app. This is my first time ever deploying something. I am getting the AttributeError mentioned above but I am clueless as to how to resolve that. I basically followed the instructions from Dashtools and now I’m stuck. Here’s my app:
GitHub - vasilmanev/DepInspector2.0
Thanks in advance to anyone who might respond!
You’re using the latest version of Flask, which is
2.3.3
. Flask has deprecated ‘before_first_request’ since
2.2.x
. Either downgrade to Flask below
2.2
or follow an alternative route like
