Description

I'm using the report-tunnel functionality, and for multiple versions (both client and server) I've been getting frequent 400 Bad Request that look like this:

Request:

{"dsn":"https://REDACTED@REDACTED/2"}
{"type":"client_report"}
{"timestamp":1642153010.09,"discarded_events":[{"reason":"sample_rate","category":"transaction","quantity":1}]}

Response with 400 Bad Request:

{
  "detail": "invalid event envelope",
  "causes": [
    "invalid item header",
    "unknown variant `client_report`, expected one of `event`, `transaction`, `security`, `attachment`, `form_data`, `raw_security`, `unreal_report`, `user_report`, `session`, `sessions`, `metrics`, `metric_buckets` at line 1 column 23"
  ]
}

What's causing this? Thanks!

Hey, thanks for writing in! This occurs because of the client reports feature, which may not be supported by your self hosted Sentry.

To disable client reports, please set sendClientReports to be false in your Sentry.init config.

Sentry.init({
  sendClientReports: false,
});

sentry-javascript/packages/types/src/options.ts

Line 134 in caba96e

sendClientReports?: boolean;

You can also filter out client_report envelopes in your tunnelling set up.

Interesting, didn't know there was a difference. Thanks!
