[Pkg-javascript-devel] Bug#929829: gulp 4 cannot build node-babel 7 - Cannot convert undefined or null to object

[Pirate Praveen]

package: gulp
version: 4.0.2-1
severity: grave
justification: it does not work at all
Control: tags -1 help

This is noticed with other packages build depending on gulp as well.

This repo can be used to reproduce the error 
https://salsa.debian.org/js-team/node-babel

I could not find a more verbose output (--verbose or -LLLL did not give 
any extra information). I need help fixing it.
