Have you change the image service to NIP96? If you select nostr.build upload service, it will try to use the old upload api. https://image.nostr.build/15588a8ca6d59e88913b3516929426ea0fbbdf4acd31c87e6fc3ffa7dd069e62.jpg
I just used default one, so I guess that’s where the problem lies
Did you know that you could also pass nip98 header to the old api and achieve the same result?
Maybe i should change the default nostr.build upload method to nip96?
That’ll work too
