Bug: Sporadic failure with "undefined" is not valid JSON

[Sainan]

Describe the bug

We use this step in GitHub-hosted ARM MacOS runners as they do not have PHP preinstalled, and it seems to be failing every once in a while with this not very helpful error message:

The error is because the action might not have been able to fetch the json manifest we have to resolve versions. If no version is specified it installs the latest version and to resolve that, it needs the manifest.

I have improved this in b595b41
