I have been trying to run ./hack/update-all.sh script and I am getting this error while updating codegen:

$ ./hack/update-all.sh 
Running in the silent mode, run with -v if you want to see script logs.
Running in short-circuit mode; run with -a to force all scripts to run.

Any idea what could be the reason behind this? Or how to resolve this issue?
