lcitool manifest references "sanity-checks.yml" but doesn't generate the file

In libnbd, I got this pipeline failure:

https://gitlab.com/nbdkit/libnbd/-/pipelines/550544496

lcitool manifest had generated this reference:

nbdkit/libnbd/ci/gitlab.yml Line 10

10

  - local: '/ci/gitlab/sanity-checks.yml'

but not corresponding file under https://gitlab.com/nbdkit/libnbd/-/tree/master/ci/gitlab
