getting a Fatal error and showing  Sidecar is unavailable. 

Based on KB article reference :

https://confluence.atlassian.com/bitbucketserver/troubleshoot-sidecar-startup-1189490619.html?utm_campaign=in-app-help&utm_medium=in-app-help&utm_source=stash 

this is what I found in Mesh logs. where it is mentioned "Git was not found on the PATH. Install Git 2.31.0+, and restart".

Welcome to the Atlassian Community!

This is what it says it is, there is no install of git in the path the environment has.  

If you do have git installed, then look at the path variable in the environment Bitbucket is running in (it won't include your git install). 

If you are not sure, then try logging into the server and running git on the command line, ideally "git -v" which should confirm what version you have there (hopefully 2.31.0+)

If you have a decent OS, then try "which git", which will return the location of the one you just asked for the version of, and that should tell you what to add to the environment path.
