yea I I thought I was doing something wrong on my end but if we are both having the same issue I'm thinking it's some sort of bug? I tried to trace the code to see why I was getting -1, but the code seem to be correct..

for what its worth I followed the esspressif docs website to send a post request to my website and I am having the same issue. my website receives the data fine, but I still get content length=1.
