We have seen several times in Cheetah SP6 Patch 2, during deployment when we upgrade the Bundle downloaded from Studio, number of functions reduces than actual, then if we again uninstall, delete and install the same build bundle again then we see all functions.
Below Pipeline we follow during deployment :
Commit from local workspace > Repository > Build > Release > Download Bundle from Artifactory > Upload in PROD > Upgrade
NOTE : We don’t pause or stop anything in PROD during deployment.
We are following the above process since long time and issue is also very intermittent, please let us know if we are missing any step or what could be the reasons for the same.
