The issue was due to an invalid or missing version reference for github.com/openshift/source-to-image. for resolving the issue add this into an go.mod file replace github.com/openshift/source-to-image => github.com/openshift/source-to-image v1.5.1
Verified via make — build completes successfully on Fedora (Linux).

added to my top level go.mod

module function

go 1.21

replace github.com/openshift/source-to-image => github.com/openshift/source-to-image v1.5.1

still getting

runtime: lfstack.push invalid packing: node=0xffff5d9db480 cnt=0x1 packed=0xffff5d9db4800001 -> node=0xffffffff5d9db480
fatal error: lfstack.push

[suhas-developer07]

add into an end of go.mod file

replace github.com/openshift/source-to-image => github.com/openshift/source-to-image v1.5.1
