I completely make a config and create a token on linode
but i got this error when try to test my fetch-test-binaries.sh

this is the message

go test -v
# github.com/slicen/cert-manager-webhook-linode [github.com/slicen/cert-manager-webhook-linode.test]
./main_test.go:20:7: undefined: dns.SetBinariesPath
./main_test.go:20:23: undefined: kubeBuilderBinPath
FAIL    github.com/slicen/cert-manager-webhook-linode [build failed]
make: *** [Makefile:15: verify] Error 2

can someone help me to resolve please ?

The error on file
main_test.go line 7 & 23 Link FIle : https://github.com/slicen/cert-manager-webhook-linode/blob/master/main_test.go

and makefile line 15 Link File : https://github.com/slicen/cert-manager-webhook-linode/blob/master/Makefile

I have tried to resolve with downgrade or upgrade my Go Version and searching but i found nothing,

I tried to just go test -v(not doing anything, just clone & go test) but i got same error

Please Help me, Thanks

SetBinariesPath was removed from cert-manager in commit cd92bf321fe14f857f34763583071e068f6c96b3

github.com/slicen/cert-manager-webhook-linode was updated to a newer version of cert-manager in commit 7131f7755b1278e48341f0d71fabac5b56b964fb - and it looks like that moved to a version of cert-manager which includes the removal of SetBinariesPath. The var declaration for kubeBuilderBinPath was correctly stripped away, but the call to dns.SetBinariesPath and a reference to the now removed kubeBuilderBinPath still remain.

So, essentially the code in main_test.go is invalid - at minimum line 20 should be removed.
