flask: GET error (exception)

[JayBrown]

Tried it again today, but got an error, when trying to download the file locally. (I'm on macOS, even though it says Firefox on Windows.) Two tests, one with "localhost", one using the local IP address.

Could it be that my installed version of flask (2.2.2) doesn't work anymore with curldrop (requirements says: 1.0.2)?

OK, that seems to have been the problem. Re-installed older versions of the required packages, and all was well again.
