What did you see instead?

Possible cause

The issue seems to be caused by GO111MODULES turned on by default. If I set GO111MODULES=off in run.bash everything works fine.

This appears to have regressed in CL 199840. Should be a pretty easy fix.

I was mistaken. The actual regression was in CL 210339.

I was mistaken again. 😅

I actually bisected the failure properly this time, and it's from CL 203820, for #34860.
