Invalid request, worked until recently

[Rage]

Im having problems fetching inv, it worked until recently. 
I found that on my alt account https://steamcommunity.com/profiles/76561199527959101/inventory/json/730/2 will result in 

{"success":false,"Error":"Unsupported request"}

However, on my main account, I would get a full list of items for CS2 that are in the inv.

Has anyone else gotten this error?

Managed to fix it by running "npm audit fix --force"
