Sentry trace header not propagated to requests made from the native layer.

Environment

How do you use Sentry? Sentry SaaS (sentry.io)

Which SDK and version? “@sentry/react-native”: “^2.4.0”,

Steps to Reproduce

1. I tried to set up Performance monitoring through Included Instrumentation.

2. I set up Sentry.

3. I connected Sentry to Navigatior.

4. That’s all what I did.

Expected Result

I would like to see sentry-trace in my request headers. None of my request has it right now. Can you, please, explain what step did I miss.

Actual Result

In Transactions tab in Performance Dashboard I see only screen names which I visit, but I don’t see any other transactions (network calls, for example). I don’t have sentry-trace headers in any of my network calls.

@laygir @kaokei As you guys are using Vue and not React Native, I guess it’s not exactly related to this issue with the React Native SDK and rather the discussion should be on the Sentry Javascript repo: https://github.com/getsentry/sentry-javascript/issues/4072. Noting that I have not been able to reproduce this issue along with no one providing reproductions I will assume it is due to creating the request on the native layer side rather on the Javascript side like I earlier hypothesized.

I will thus rename this issue and move it to our Backlog.

Hey @kaokei 👋

I have been in touch with Sentry support and recently concluded a month long e-mail thread precisely about this behaviour. Also have created the issue below and it’s been acknowledged by Sentry and support told me that it is in the backlog and will be fixed soon. I hope they fulfill this promise.
