Cache not saving despite successful dependency step

[aschmidt-amplify]

STOP

If you are debugging a failed build or have a question about GitHub Actions in general do NOT open an issue here. Either post on the Actions sections of the GitHub Community or the RStudio Community forums.

Open an issue here only if you have a bug in one of the custom R specific actions themselves.

Describe the bug When a workflow runs, I do not see a stored cache, even if the workflow is successful. In the logs, I see:

Cache not found for input keys: Windows Server 2022 x64 (build 20348)-R version 4.4.1 (2024-06-14 ucrt)-1-0aab29eb803e797a0ac7c390c4d654267026b8bed8c76d5d72559ffed7c1e929, Windows Server 2022 x64 (build 20348)-R version 4.4.1 (2024-06-14 ucrt)-1-

Note: I see this for macos and ubuntu, too

To Reproduce You MUST include a link to the full logs of the failed build. Bug reports which do not contain a link, or only contain a screenshot of the failed build will be closed.

Expected behavior Dependencies are cached
