Okay, now that I was able to get the Python version of LangChain instrumentation working, I wanted to get the same working for TypeScript following this documentation.
I am testing this in a Deno Jupyter notebook:
/*instrumentation.ts */
import { LangChainInstrumentation } from "npm:@arizeai/openinference-instrumentation-langchain";
import { ConsoleSpanExporter } from "npm:@opentelemetry/sdk-trace-base";
import {
NodeTracerProvider,
SimpleSpanProcessor,
} from "npm:@opentelemetry/sdk-trace-node";
import { Resource } from "npm:@opentelemetry/resources";
import { OTLPTraceExporter as ProtoOTLPTraceExporter } from "npm:@opentelemetry/exporter-trace-otlp-proto";
import { diag, DiagConsoleLogger, DiagLogLevel } from "npm:@opentelemetry/api";
import * as CallbackManagerModule from "npm:@langchain/core/callbacks/manager";
// For troubleshooting, set the log level to DiagLogLevel.DEBUG
diag.setLogger(new DiagConsoleLogger(), DiagLogLevel.DEBUG);
// Your Arize Space and API Keys, which can be found in the UI
// metadata.set('space_key', 'your-space-key');
// metadata.set('api_key', 'your-api-key');
const provider = new NodeTracerProvider({
resource: new Resource({
// Arize specific - The name of a new or preexisting model you
// want to export spans to
"model_id": "Aporia_Testing",
"model_version": "1.0"
}),
});
// add as another SpanProcessor below the previous SpanProcessor
provider.addSpanProcessor(
new SimpleSpanProcessor(
new ProtoOTLPTraceExporter({
// This is the url where your phoenix server is running
url: "http://192.168.1.69:6006/v1/traces",
}),
),
);
const lcInstrumentation = new LangChainInstrumentation();
// LangChain must be manually instrumented as it doesn't have
// a traditional module structure
lcInstrumentation.manuallyInstrument(CallbackManagerModule);
provider.register();
@opentelemetry/api: Registered a global for diag v1.8.0.

Any thoughts on this object is not extensible error?
