Filecoin Payment Channel Investigations

I'm using this codebase to invesigate interacting with filecoin payment channels. Currently I'm trying (and failing 😕) to get a payment channel to open.

Reproducing the problem

I've followed the instructions here to setup a local lotus devnet:

▶ git clone git@github.com:filecoin-shipyard/lotus-devnet.git
▶ cd lotus-devnet
▶ git rev-parse --short HEAD
73b3ebe
▶ make devnet BIGSECTORS=false

To get going with this codebase you'll need node and yarn installed. You can then run

▶ yarn

to install the dependencies and then yarn start to run this code.

I'd expect this to open a payment channel. Instead I get an error with ExitCode: 16.

▶ yarn start
yarn run v1.19.0
