Custom error handler nextJS

[LeikoDmitry]

Hi, there
I have a one question, could you please show me How I can implements the custom error handler when nextJs build the project and send the source map?

Best regards, Dmitry

Hey @LeikoDmitry, thanks for writing in. What are you referring to as custom error handler here - is it for client or server side? I would recommend just following the Next.js docs here, anything you do should just work in Sentry and sourcemaps out of the box.

The Sentry SDK's expose a beforeSend hook that can mutate an error event before it's being sent to Sentry.

I mean, when I build a project, sentrySDK sends source map to server via API, but when my server may be unavailable, it crashes with error about inability to send and project build crashes. How to make a handler for this error so that the build doesn't crash.

Please take a look at the errorHandler option in the webpack plugin options of withSentryConfig:

withSentryConfig(nextConfig, {
  errorHandler: (err) => {
    // handle error
  }
})

@lforst Thank you!
I'll write back later if that helped.
