Hi all. The answer was simple enough. I tried to send an image thinking it had a small size. Instead, it’s about 1.8MB (it should be sent even if it’s not very small, or it’s not supposed to be sent?) and it caused 413 error. Can you pls tell me what’s the size limit? For this app, it’s supposed to send only small images (about 32KB) and so 413 error shouldn’t be hit, but what if I need to send larger images?
