Hi Everyone,

I am trying to create additional trace spans inside my gRPC rpc methods. I reviewed the API docs and examples but have not seen any firm guidance or working implementation. When I do call trace#createChildSpan, a null is returned. What am I doing wrong here? Here is an abbreviated code block from my server.js file:

const traceApi = require("@google-cloud/trace-agent").start({ projectId: "festivals-183900", keyFilename: googleSvcAccount }); server.addService(smtpTemplateProto.templatesPackage.SmtpTemplateSvc.service, { addBindable: (call: any, cb: any) => { let clientCn: Client; let data: Object; let rollBack: boolean = false; let spanAddBindable: any; try { // create spanAddBindable span spanAddBindable = traceApi.createChildSpan({ name: "Svc.BindableController#addBindable" }); console.log(spanAddBindable); <== evals as null! spanAddBindable.endSpan(); } catch(err) {} } }
