#20503 Deleted files cause `pants tailor` with `--changed-since` to fail Issue created by blimmer Describe the bug I use the following command in CI to validate the monorepo, as recommended by the docs:

> pants \
	  --changed-since=origin/main \
	  tailor --check \
	  update-build-files --check \
	  lint

However, if I delete a package, including its

BUILD

file in a PR, the

--changed-since

flag causes

tailor

to try to run on those files, which

pants

blows up on:

16:40:57.91 [ERROR] 1 Exception encountered:

Engine traceback:
  in `tailor` goal

IntrinsicError: Unmatched glob from `--changed-since`: "aws/projects/my_project_name/*"

Do the file(s) exist? If so, check if the file(s) are in your `.gitignore` or the global `pants_ignore` option, which may result in Pants not being able to see the file(s) even though they exist on disk. Refer to <https://www.pantsbuild.org/v2.19/docs/troubleshooting#pants-cannot-find-a-file-in-your-project>.


Exited with code exit status 1

If files are deleted, yes, they are changed, but they shouldn't throw an error. Pants version 2.19.0 OS Linux (CircleCI Ubuntu executor) Additional info N/A pantsbuild/pants
