Hello, I put | symbol in my git user.name.
I broke the response from revision metadata api of argo server
/api/v1/applications/${reponame}/revisions/${commitid}/metadata?appNamespace=${namespace}

So that it returns

{"author":"PSy ","date":"1970-01-01T00:00:00Z","message":"1689860699|fix: do not use deploy in app label"}

This is cause by https://github.com/argoproj/argo-cd/blob/f8f9ae9accd413b417be1d188418f2b3b7c25e63/util/git/client.go#L632C38-L632C63

resp. the git show format expression --format="%an <%ae>|%at|%B" that is then split by |.

I suggest to rewrite the method without such formatting.
