Context Propagation sample not working

We use jwt for authentication which means that workflows and activities need to carry around jwt token of the function that triggers them.

I tried adapting the sample to no avail. then tested the sample and it doesn’t work correctly.

logs below;

Thanks a lot for letting us know. Let me take a look to see if the problem is with the sample of the SDK itself.

It looks like the sample forgets to configure the context propagator with the client. Make sure that it is included into client.Options:

c, err := client.NewClient(client.Options{
       HostPort:           client.DefaultHostPort,
       ContextPropagators: []workflow.ContextPropagator{ctxpropagation.NewContextPropagator()},
})

@Cully please track this

It looks like context propagation is broken in the TestSuite. Filed an issue to get this fixed.

Here is the fix for the sample itself: https://github.com/temporalio/go-samples/pull/39
