Please guide me

Looks like a Python issue. Check which version of Python are you using, also which version of the FreeTAKServer_Manager are you using?

Double check the MainConfig.py and the config.py files if there's no Python conflict usually the error is in those files.

[arazi2021]

I'm using Python 3.8.9

[lonewaffle]

Did you ever figure this out? I'm having the same issue. Python 3.8.9, FreeTAKServer_Manager v1.0.0.5. My MainConfig.py and config.py are bone stock, so I'm not sure what to look for.

[Cale-Torino]

@lonewaffle @arazi2021 Strange I have tested my releases and can't reproduce.

What version of windows and are you using the WinForms or WPF Version?

Also check if you selected the .yaml option *Note you will have to setup the .yaml file if this is the case.

( I made a note on the repo page about selecting the .yaml file. https://github.com/Cale-Torino/FreeTAKServer_Manager)

You select the config when you first run the server.

Also please note I tested the software using Python 3.8.10

[lonewaffle]

I'm using the WinForms version on a clean install of Windows 10 LTSC 2021 (21H2). I don't remember being prompted to choose to use the YAML file or not. Perhaps it's not getting that far in starting the server for the first time?

I will switch to Python 3.8.10 and see if that helps.

[Cale-Torino]

@lonewaffle @arazi2021 Let me know if it works

[lonewaffle]

Unfortunately 3.8.10 didn't help. Out of curiosity, what version of Windows are you testing with? I'm also seeing the same issue when I test on a Windows 11 computer, so I'm wondering if something changed in later builds of Windows that's causing this issue.

[lonewaffle]

I just found that the issue is with markupsafe. They apparently removed soft_unicode from the current release and now you have to specify 2.0.1 when installing to still have support for it. Removing the installed version and installing 2.0.1 removes this error and instead give the error: ImportError: cannot import name 'json' from 'itsdangerous'

This lead me to this page: https://itsmycode.com/importerror-cannot-import-name-json-from-itsdangerous/

I followed the advice and installed Flask 1.1.4 and now it's working.

So, in summary, I did the following:

pip uninstall markupsafe
pip install markupsafe==2.0.1
pip install Flask==1.1.4

and now the server starts.

@lonewaffle That's good news. There's a list of all the required Python libraries in the requirements.txt file if you are interested they are automatically installed with the server.
