Sentry.init()

export const sentryConfig: ReactNativeOptions = {
  dsn: staticConfig.sentry.dsn,
  tracesSampleRate: staticConfig.sentry.tracesSampleRate,
  dist: getBuildNumber(),
  environment: Config.VP_ENVIRONMENT,
  release: `${Config.BUNDLE_ID}@${getVersion()}`,
  // Don't report errors in dev mode
  enabled: !isDev(),
  beforeSendTransaction: excludeAppStartFromTransaction,
  integrations: [
    // Enables performance monitoring
    reactNavigationIntegration,
  ],
};

Steps to Reproduce

Call Sentry.addBreadcrumb() with the type property set. (I have tested with type "default", "http" and type "navigation").

Expected Result

Only one breadcrumb should be showing in the list of breadcrumbs for an event.

Actual Result

The breadcrumbs where the type property has been set are duplicated in the list of breadcrumbs for an event.

Example:

Note:
When calling Sentry.addBreadcrumb() without the type set, then only single breadcrumbs are being logged, as expected.

Hi @gimi-anders,
thank you for the message,

I've tried reproducing the issue using the following code, but only one breadcrumb was recorded.

Sentry.addBreadcrumb({
  message: 'Breadcrumb message with type',
  type: 'default',
});

Would you be able to share a reproducible example?

How can I share an example the best way?

My current project is a big and complex project that I cannot share. Is there some way I can create a small sharable project?
