Fixes #

Issue #32846
Updated error code to include "Did you mean..." assistance.

Sorry, there may have been a misunderstanding. The original issue isn't that the existing error message is wrong. The suggestion is to add a new message and appropriately issue it under the conditions I outlined. Feel free to iterate and get back to us when you have things working, new tests have been added, and the tests pass.

By the way, as a heads up your commits don't seem to be associated with your GitHub account. While this isn't technically a problem, you might care if you want more appropriate attribution. You can either make sure your GitHub account is associated with the email address you're using for your commits, or rebase and amend your commits to fix the author name and email.

Thanks for this PR @sterlingfs - I've just merged #33171 which also addressed the same issue!
