@channel Hello team, the below function is getting in red color while integrating with the react project registerInstrumentations({ instrumentations: [ new FetchInstrumentation({ propagateTraceHeaderCorsUrls: ["/.*/g"], clearTimingResources: true, applyCustomAttributesOnSpan: ( span: Span, request: Request | RequestInit, result: Response | FetchError ) => { const attributes = (span as any).attributes; if (attributes.component === "fetch") { span.updateName(
${attributes["http.method"]} ${attributes["http.url"]}
); } if (result instanceof Error) { span.setStatus({ code: SpanStatusCode.ERROR, message: result.message, }); span.recordException(result.stack || result.name); } }, }), ], });

@Mohit Verma I think you are facing issues with not setting up the libraries correctly. Can you try instrumenting a simple app before getting more complex. May be just instrument a sample
create-react-app

oh, what are the error messages? Is SigNoz installed correctly? Also, can you run this troubleshooting binary where you are running your application and share what output you get? https://signoz.io/docs/install/troubleshooting/#using-troubleshooting-repository
