Hi @or-shachar, this looks good to me. Can you add a CHANGELOG entry to the terraform/.changes/v1.12 directory? Due to the release schedule, we'd aim to release this in v1.12.1 next week. Thanks!

@liamcervante can we backport this also to 1.11 ?

[liamcervante]

With the release of v1.12.0 yesterday, we don't have plans for any more v1.11 patch releases so a backport doesn't really make sense.
