unable to execute a bash script in k8s cronjob pod's container - bash

Question

Team,
/bin/bash: line 5: ./repo/clone.sh: No such file or directory
cannot run above file but I can cat it well. I tried my best and still trying to find but no luck so far..
my requirement is to mount bash script from config map to a directory inside container and run it to clone a repo but am getting below message.

Assuming the working directory is different thant /:
If you want to source your script in the current process of bash (shorthand .) you have to add a space between the dot and the path:
. /repo/clone.sh
If you want to execute it in a child process, remove the dot:
/repo/clone.sh
