How to get custom tags that was set in Sentry

I'm using Sentry to track errors on my app and I set custom tags when I initialize Sentry.

Sentry.setTag('custom', 'custom tag value');

Later on in the app, I need this custom tag value, is there a way for me to retrieve it back? I've tried Sentry.getTag('custom') and it doesn't work. I've been looking at their documentation and I can't find any.

Solution

  • Sentry.getIsolationScope() gets you an object similar to this:

    const a = Sentry.getIsolationScope()
console.log({a})

{
  a: Scope {
  _notifyingListeners: false,
  _scopeListeners: [],
  _eventProcessors: [],
  _breadcrumbs: [],
  _attachments: [],
  _user: {},
  _tags: { custom: 'custom-value' },
  _extra: {},
  _contexts: {},
  _sdkProcessingMetadata: {},
  _propagationContext: {
  traceId: 'some_id',
  spanId: 'another_id'
  },
    _level: undefined,
    _span: undefined,
    _session: undefined,
    _transactionName: undefined,
    _fingerprint: undefined,
    _requestSession: undefined,
    _client: undefined
  }
}
