Const initializer 'protoimpl.EnforceVersion(20 - protoimpl.MinVersion)' is not a constant

I'm new to gRPC, trying to generate go code from protos and getting this error on the generated file

Generated code with issue:

//  protoc-gen-go v1.25.0
//  protoc        v3.12.3
const (
    // Verify that this generated code is sufficiently up-to-date.
    _ = protoimpl.EnforceVersion(20 - protoimpl.MinVersion)
    // Verify that runtime/protoimpl is sufficiently up-to-date.
    _ = protoimpl.EnforceVersion(protoimpl.MaxVersion - 20)
)

Error

Const initializer 'protoimpl.EnforceVersion(protoimpl.MaxVersion - 20)' is not a constant

The cause was a bad version of the package google.golang.org/protobuf The solution is to get the latest version

go get -u google.golang.org/protobuf/proto
