Facing issue while running release-sdk.h (No such file or directory)

Hello, there I am trying to build my own custom SDK using jitsi repository.
And I have fetched the depended file using npm install. The command was run in the root folder.
And it was successfully executed.
But when I tried running this command:

>./android/scripts/release-sdk.sh /tmp/repo

It said:

> grep: /Volumes/Macintosh: No such file or directory
> 
> grep: HD: No such file or directory

Kindly help.
