Error object change is basically cherry picking d242156 merged in next previously.

@kwonoj what is dependency cruiser? Is it required for this change? Can we discuss it and perhaps move it to a different PR?

[kwonoj]

@benlesh it's replacement to madge for circular ref check. It should be included in this PR, cause madge has inner peer dep prevented to bump up ts recently. (Jay hits this). Course we can discuss if needed, but not as a separate PR.

[benlesh]

@kwonoj right on
