add runtime checks for `--fec-params` in `komodo prove`
@n.dissoubray found a bug when not passing --fec-params
to komodo prove
where
-
null
cannot be accessed - invalid keys in
$fec_params
might be accessed and crash the command
this MR adds runtime checks for the type of --fec-params
, to make sure it's
- non
null
- has a valid shape
