Frozen application can't run

[Brinfer]

Description

I’m trying to distribute my python server that uses connexion with pyinstaller.

Unfortunately, the executable product not pyinstaller does not work. Of the first request an error 500 is issued while it is not in "normal" mode.

Expected behaviour

connexion should work once compile with PyInstaller as Flask.

Actual behaviour

There seems to be an error when instantiating blueprint.
Whatever the basic url, the same error comes back.

Steps to reproduce

Create a simple project on the model of the example helloworld (helloworld.zip)
Run the pyinstaller command line:

pyinstaller\
    helloworld/__main__.py\
    --add-data helloworld/spec:spec\
    --collect-all connexion\
    --name helloworld\
    --onefile

and run the executable:

./dist/helloworld
