[Discourse] ERROR json: cannot unmarshal object into Go struct field CategoryModel.category_list.categories.subcategory_list.uploaded_logo of type string

[cmollet]

Steps to reproduce:

1. Connect a Discourse system (in my case, discourse.nixos.org )
2. Attempt to view posts
3. "No items found" displays on UI; error log gives

[mrusme]

The API responds with uploaded_logo set to null: https://discourse.nixos.org/categories.json?include_subcategories=true

Neon Modem expects it to be a string though. The official API doc says string or null, hence will need to adjust the parsing in Neon Modem.

@cmollet if you can, try the latest master branch and report back in case it should still be failing!

Thanks, @mrusme , unfortunately it seems the issue still persists. Running the neonmodern binary resulting from running make on commit hash 408cbd2 gives

FWIW, I just removed

UploadedLogo              
UploadedLogoDark            
UploadedBackground 

from the CategoryModel and that did the trick, because I don't think those fields are actually being used at the moment

[mrusme]

I see, I'll keep this issue open as this needs to be fixed either way. Thank you for reporting!
