Error "loading error: bundle bundle-msys.tar.gz: verification key not provided" occurred，when Load signed bundle in golang，

[woshizilong]

This is my go source sample.

import "github.com/open-policy-agent/opa/rego"
......
query, err = rego.New(
		rego.LoadBundle("bundle-msys.tar.gz"),
		rego.Query("x = data.main.allow"),
		rego.Compiler(compiler),
		// rego.SkipBundleVerification(true),
	).PrepareForEval(ctx)

If make rego.SkipBundleVerification(true) available, no error will occur.But can't verify the bundle anymore.
How should I provide a valid certificate for verification?

Hi @woshizilong ! Did you look into using the SDK for this? That should provide you with all the capabilities of the OPA server, including loading a config file for this purpose.

@anderseknert
Thanks for your answer.
I have used the sdk and it works fine. But there are many more packages imported. I want to reduce external dependencies.
