@sentry/gatsby build can fail with "TypeError: invokeErr is not a function" when paired with @sentry/webpack-plugin 5.1.1

Is there an existing issue for this?

• I have checked for existing issues https://github.com/getsentry/sentry-javascript/issues
• I have reviewed the documentation https://docs.sentry.io/
• I am using the latest SDK release https://github.com/getsentry/sentry-javascript/releases

Reproduction Example/SDK Setup

No response

Steps to Reproduce

Install:

• @sentry/gatsby: 10.46.0
• gatsby: 5.16.1

Run a Gatsby build which will trigger a Sentry error and observe that the build will fail with this error:

error UNHANDLED REJECTION invokeErr is not a function

TypeError: invokeErr is not a function
 at Object.errorHandler ([repo]/node_modules/@sentry/gatsby/gatsby-node.js:58:13)
 at handleRecoverableError ([repo]/node_modules/@sentry/bundler-plugin-core/dist/cjs/index.js:5728:48)
 at async Object.uploadSourcemaps ...

This is because the error handler code (in @sentry/gatsby/gatsby-node.js:58:13) is passing two arguments:

errorHandler(err, invokeErr) {
 ...
 invokeErr(err);
}

However, the recently updated @sentry/bundler-plugin-core calls options.errorHandler with only a single Error argument:

options.errorHandler(unknownError)

This mismatch causes builds to fail because invokeErr is undefined.

Expected Result

The real/underlying Sentry error should be surfaced rather than the build failing due to this issue. It should not fail with "invokeErr is not a function".

Actual Result

The error is not handled and the build process fails.

Additional Context

Suggested fix: update the errorHandler in @sentry/gatsby to match the updated webpack plugin API.
