Thanks for the answer. Somehow I missed the Protocol Buffers Well-Known
Types page in the docs / protobuf website.
I still have issue creating an instance of the message. For example if I
have a plain object:
{
firstName: 'Bob'
lastName: 'Smith',
email: '[email protected]',
metadata: {
foo: 'bar',
active: true
}
}
And I try to create an instance of the message (to be sent via grpc) I get
error
.google.protobuf.Struct#foo is not a field: undefined
Same thing if I use google.protobuf.Value. I've tried numerous ways of
doing this but can't seem to accomplish it. I must be missing something.
Anyone have any ideas.
Thanks for the help again.
