both reading properties and checking existence could have retry mechanism to avoid such problems
https://github.com/wttech/gradle-aem-plugin/issues/834#issuecomment-1144957002 fixed by #905
initial issue seems to be fixed. instance deploy is now checking stability before. but node existence checking need to have retry mechanism for sure and that need to be improved.
Current error, while performing backup recover to running instance:
Execution failed for task ':env:instanceUpgrade'.> Cannot check repository node existence: /var/gap/package/deploy/c11484cb on LocalInstance(name='local-publish', httpUrl='http://localhost:4503'). Cause: Failed request to HEAD http://localhost:4503/var/gap/package/deploy/c11484cb.json HTTP/1.1! Cause: Unexpected status code '503' while checking node '/var/gap/package/deploy/c11484cb' existence on LocalInstance(name='local-publish', httpUrl='http://localhost:4503')!

this line need to be protected with retry mechanism; this is caused because deployAvoidance feature which could be disabled to avoid the error for now
for the initial error, how about increasing default actionRetry from 1 to 3?
