Contributor There was a problem hiding this comment. SInce you're mutating the config here, you'd have to call ContributorAuthor There was a problem hiding this comment. Thanks, I will update it! Could you elaborate what is the difference between this mutation and normal assignment to struct. Seems that it works good in both cases but I may miss some context ContributorAuthor There was a problem hiding this comment. Discussed with Pieter that it's better to skip dynamic assignment here in favor of simplicity, but I can update it in another PR if it doesn't feel right | ||

ContributorAuthor There was a problem hiding this comment. Added warning for cases when Contributor There was a problem hiding this comment. Please include a comment saying that this mutator runs before these fields are defaulted. I was puzzled by this but then found it is run before the mutators that populate its default value. | ||

Contributor There was a problem hiding this comment. Same issue as above w.r.t. the path not existing. ContributorAuthor There was a problem hiding this comment. Seems like it works fine, or do we expect other behavior here?   Contributor There was a problem hiding this comment. Ah, I was confused by the path including This call site and the one above index it with It looks like it is not used in full, so the first two elements can be removed from the assignment. | ||

This won't work -- the
targetsfield is cleared after selecting it.But because the target is merged into the main configuration, you can use
presets.source_linked_deploymentdirectly and it will return the original location.
