Not sure why this genhash file isn't in sync with how this runs

If you run bin/gencode check locally does it work?

[noursaidi]

I think there was an update without a gencode - I've got a documentation PR #312 which also fixes this

[johnrandolph]

can we re-run these checks

[noursaidi]

@johnrandolph tests now pass
