The content looks like this on Blackboard:

I assume the issue here is related to the title of the content having slashes. However not all content like that fails to download.

[sanjacob]

Thanks for your report. I'll look into it.

[sanjacob]

Can you show me how the file structure looks for this content?

[ColeAnthonyCapilongo5735]

The folder path is <sync folder>/2024/<course>/Learning Materials/labs/Lab 02_Examples_pluginShell.c A shell that dynamically loads functions/pluginShell.c A shell that dynamically loads functions/. Within that folder there is only one file, called pluginShell.html.

[sanjacob]

A fix is coming

[sanjacob]

Hi there, can you try out 0.17.1-rc.1? It's available in the releases section or even on pypi. You may need to delete your configuration file (~/.config/blackboard_sync) and your previous downloads

Just let me know if this content is downloaded correctly, and if you have any further download exceptions.

[ColeAnthonyCapilongo5735]

Definitely downloaded more content, but I did get this error, maybe unrelated:

TypeError: can only concatenate str (not "NoneType") to str

This is without deleting config or previous downloads.

[ColeAnthonyCapilongo5735]

@sanjacob ok I'm still getting "is a directory" errors with 0.17.1 unfortunately

[sanjacob]

@ColeAnthonyCapilongo5735 you need to delete all your downloads and start from scratch. Delete your config file too.

[sanjacob]

Were you able to fix it?
