Heya, I'm trying to use pre-signed POSTs with R2 to have users directly upload images to my bucket. Thanks to some posts here I have the CORS portion working fine, but when now when I attempt the upload I get back a
400
400
with
Invalid Argument: Authorization
Invalid Argument: Authorization
. Am I supposed to be putting something in the Authorization header? Appreciate any help, will post the entire request log in a thread
