croc: problem with decoding: unexpected end of JSON input

Describe the bug I get problem with decoding: unexpected end of JSON input when trying to send files.

To Reproduce Steps to reproduce the behavior:

1. Get a shell with croc in PATH (see below)
2. Send and receive a file or folder, preferably on the machine itself

Expected behavior It just works

Version croc version v8.1.1-e250eee

Get a shell with that version installed using: NIX_PATH=nixpkgs=https://github.com/nixos/nixpkgs/archive/c4364cdddc421dfdb4a60fda38ed955abce1603a.tar.gz nix-shell -p 'with (import<nixpkgs>{});buildGoModule rec {pname = "croc";version = "8.1.2";src = fetchFromGitHub {owner = "schollz";repo = pname;rev = "v${version}";sha256 = "0m7kgfmdbmz0r0dydz7j9cllp77076qgdcmkw3jnrsj169f5acfa";};vendorSha256 = "1fjv4y7pkwd4wsq3y66r75gr0makhjcdf0i3cpxgv03x5ahkf16b";doCheck = false;subPackages = [ "." ];}'
