How to set up Google Cloud Functions integration with V7

[pkruithof]

Hi, we've been using Sentry to monitor our cloud functions. Up to now the following setup has worked perfectly fine:

const {GCPFunction} = require('@sentry/serverless');

GCPFunction.init({
  dsn: process.env.SENTRY_DSN
});

const eventHandler = async (data) => {
  // do something...
}

exports.publish = process.env.SENTRY_DSN
  ? GCPFunction.wrapCloudEventFunction(eventHandler)
  : eventHandler
;

However upgrading to V7 broke this, ironically generating a Sentry issue:

I dove into the upgraded library to see what I need to change, as the migration guide does not mention this part. But I cannot figure it out, and my lack of Typescript/JavaScript knowledge isn't helping here. Also, the documentation is very sparse on this subject, unfortunately.

What I did figure out was that the wrapping is now supposed to be like this:

GCPFunction.wrapCloudEventFunction(
  (context, callback) => {}
)

Only I don't know what to do with this callback, and where/how to pass my event handler to get this to work. Any help would be greatly appreciated.
