I have uploaded a CodeIgniter project on google cloud APP engine with Flexible Environment
Getting bellow error, while connecting the SQL Instance

Have experienced the same case with a Symfony 4 project. My findings on that:
When I first deployed the app on the App engine and the hostname was set:
'hostname' => 'localhost'
I got this error:
SQLSTATE[HY000] [2002] No such file or directory
Afterwords I just removed the above line ('hostname' => 'localhost') and deployed the app again. This worked for me
On the next deployments I added again the hostname with localhost and it worked.
Conclusion
