ci: invalidate circleci caches to prune nested node_modules (#46707)

devversion · dylhunn · commit 2548214ba230 · 2022-08-08T09:23:56.000-07:00
Yarn 1.x. is known to not prune nested unused node modules. This throws off Bazel when the dependency tree changes but there are leftover unused nested node module folders. This causes CI failures currently after the dependency tree updates. Invalidating the cache fixes this issue. Long-term a switch to Yarn 2.x+, pnpm will fix this. PR Close #46707
