Merged my changes, this is the build -> https://dnceng.visualstudio.com/internal/_build/results?buildId=778994&view=results

[riarenas]

Any idea how long this will take to fix?

@epananth should have an estimate once she takes a look

Can the break be reverted until the change is validated?

My preference is on reverting the changes related to v3 too, unless it’s an obvious thing that was missed. (There were already two merge errors with the PR, I wonder if this is just more of them)

Who is working on this?

Should be @epananth.
