Is it possible to use putFile without logging in? I’m looking for a way for visitors to be able to write data. I was able to get putFile working when logged in but when I logged out it stopped working and I get the error: “InvalidStateError: Missing userData”.
You can generate an address and use that for the app bucket. However, each visitor of your app will write to the same storage and know the private key (if they look into the code).
