Hello,
This error typically arises when you use a version of Go that is older than 1.16, as older versions do not include the "io/fs" package.

You can try to Update Go Version: Ensure that you are using Go version 1.16 or newer. You can check your current Go version by running go version in your terminal. If you are using an older version, you should update it to at least 1.16.

Please let me know if this helps, Bobbi
