@Amulyam24 The checks are failing due to

go: module ../../../.. listed in go.work file requires go >= 1.22.0, but go.work lists go 1.22; to update it:

I guess you need to update the following files:

• https://github.com/oras-project/oras/blob/main/test/e2e/go.mod
• https://github.com/oras-project/oras/blob/main/test/e2e/go.work
