Observed in [this cloud build](https://pantheon.corp.google.com/cloud-build/builds;region=us-central1/d888fcee-9958-46ac-a6b1-30557c0fe949;step=0?e=-13802955&mods=logs_tg_prod&project=oss-fuzz-base) required by [this PR](https://github.com/google/oss-fuzz/pull/12405#issuecomment-2311293319).

Start with the cloud build linked in the issue and the dependency-related context in PR #12405. Inspect the project’s Python dependency declarations and reproduce the reported resolver errors; done means the cloud build completes without incompatible google-cloud dependency versions.
