I suggest you look at the actual request body which the client is sending,
using your browser's developer console (or at worst using
tcpdump/wireshark, as long as it's not HTTPS).
Then it should be clear whether your Javascript is sending a "parcelas"
form value, and if so what it contains. I note that you've passed a
Javascript array (parcelasTabela) without JSON.stringify'ing it, so you'll
have to see what it actually sends, if anything. My guess is that your
issue is with the Javascript, not the Go.
Given that this is a complex structured value, it might be better to make
the whole request use JSON instead of form data though.
