Link to Sentry event

Customer Event

SDK Setup

Sentry.GCPFunction.init({
  dsn: "https://<>@o478484.ingest.sentry.io/<>",
  tracesSampleRate: 1.0,
  environment: process.env.<VAR>,
  release: `<HIDDEN>`,
  integrations: defaults => defaults.filter(integration => integration.name !== "Console"),
});

Steps to Reproduce

Context:
Customer trying to set the serverless Function Name as a tag, because the cloud function’s name is not on the event / they don’t know which Cloud Function (GCP) it came from.

Problem:
Set a custom tag, and it doesn’t appear on the Issue.event in Sentry.
ProblemUnderlying (Optional)
Maybe if the Function Name could appear by default in a tag, then the customer would not be trying to set a custom tag for it. Is that something we could make happen?
When an error occurs in a web server /endpoint (not Serverless architecture) you know where it occurred because of the tags

url:http://
transaction:

But in a serverless function error, the Cloud Function / Lambda name is equivalent to the url endpoint, in the user’s mind? And there’s no Function Name on the event? The stacktrace alone doesn’t guarantee you can figure out which URL/Endpoint or Cloud Function it came from, or does it?

Expected Result

Custom Tag should appear on the event linked

Actual Result

Custom Tag does not appear on the event linked
