So "crypto/rsa: verification error" likely came from the HTTPS requests made to pull down the Google public certs for verification

google-api-go-client/idtoken/validate.go

Line 168 in ed3a635

certResp, err := v.client.getCert(ctx, googleSACertsURL)

. This could be from your system root certs being out of date - pulling the Google certs uses the default Go client.

Or, probably more likely, it came from the actual verification of the id token you provided it, from here

google-api-go-client/idtoken/validate.go

Line 189 in ed3a635

return rsa.VerifyPKCS1v15(pk, crypto.SHA256, hashedContent, sig)

It is an intentionally vague error so you will have to do some debugging. Not much more I can do without extra logs.
