Hello. I'm using getInventoryContents from node-steamcommunity to get my bot's inventory, game ID 730, context ID 2, also using language set to 'english', and I keep getting HTTP 400 error when invoking that method.
While debugging, I narrowed it down to this endpoint call:
https://steamcommunity.com/inventory/765611988xxxxxxxx/730/2?l=english&count=5000
The query part is what seems to cause issues, removing it returns JSON content as expected.
P.S. Solved, needed an update.
