SDK Setup

Sentry.init({
  dsn: SENTRY_DSN,
  environment,

  // Adjust this value in production, or use tracesSampler for greater control, default: 1
  tracesSampleRate: 0.1,

  // Setting this option to true will print useful information to the console while you're setting up Sentry.
  debug: false,

  replaysOnErrorSampleRate: 1.0,

  // This sets the sample rate to be 10%. You may want this to be 100% while
  // in development and sample at a lower rate in production
  replaysSessionSampleRate: 0.1,

  // You can remove this option if you're not planning to use the Sentry Session Replay feature:
  integrations: [
    new Sentry.Replay({
      // For additional Replay configuration see https://docs.sentry.io/platforms/javascript/session-replay/configuration/
      maskAllText: false,
      blockAllMedia: false,
    }),
    new Sentry.Feedback({
      // For additional SDK configuration see https://docs.sentry.io/platforms/javascript/user-feedback/configuration/
      colorScheme: 'dark',
      showBranding: false,
      themeDark: {

Expected Result

Feedback gets sent

Actual Result

Error: There was a problem submitting feedback, please wait and try again.

Sadly also nothing in the console that would help me debug. I tested this locally and on a vercel preview deploy.

I have Early Adopter enabled:

And I do have Vercel previews and localhost in the allowed domains:

*-SITENAME.vercel.app
localhost

Seems to work now..weird. Maybe the allowed domains took a while to kick in. I would appreciate though if the error message was a little more descriptive and this was easier to debug, leaving the ticket open because of that. If you'd rather have me make a new one just for that, please let me know.

@billyvg @c298lee you mind taking a look at this?

We'll take a look and see if it's allowed domains related.
