Cannot Sentry in serverless function

Simple serverless function:

1import { VercelRequest, VercelResponse } from '@vercel/node';2import * as Sentry from '@sentry/node';34export default async function functionSentry(5	request: VercelRequest,6	response: VercelResponse,7) {8	Sentry.init({9		dsn: 'https://dsn_value@sentry.onpremise.org/66',10		environment: process.env.NODE_ENV,11		serverName: 'trololo',12		release: '0',13		debug: false,14		// Add Tracing by setting tracesSampleRate15		// We recommend adjusting this value in production16		tracesSampleRate: 1.0,1718		// Set sampling rate for profiling19		// This is relative to tracesSampleRate20		profilesSampleRate: 1.0,21	});2223	Sentry.captureException(new Error('test'));2425	throw new Error('test2');26}

Calling the corresponding endpoint does not generate any issues in Sentry.

Naturally, the Sentry server works, and if the function is run without Vercel, issues are generated in Sentry.

I assume that Vercel kills the function process after exception as well as after response.send(). But, what to do?

Hello, same issue here. I did manage to get errors in though via

1import * as Sentry from "@sentry/serverless";23export const initSentry = () => {4    Sentry.init({5        environment: process.env.VERCEL_TARGET_ENV || 'unknown',6        dsn: process.env.SENTRY_DSN,7        tracesSampleRate: 1,8        profilesSampleRate: 1,9    });10};

with

1export async function POST(req: Request) {2  initSentry();3   ...

However, we still do not have tracing working.

Emphasis on waitUntil(Sentry.flush(5000)); Code example:

1try {23  someFunc();45} catch (error) {6  Sentry.captureException(error, {7    extra: {8    method: request.method,9    url: request.url,10    headers: request.headers,11    body: request.body,12    query: request.query,13    cookies: request.cookies,14    },15  });1617  response18    .status((error as ExtError).status || 500)19    .json((error as ExtError).statusText || 'Internal Server Error');20} finally {21  waitUntil(Sentry.flush(5000));22}
