Warning when using hideSourceMaps option in next.config.js

[simontaisne]

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

How do you use Sentry?

Sentry Saas (sentry.io)

Which package are you using?

@sentry/nextjs

SDK Version

7.7.0

Framework Version

12.2.3

Link to Sentry event

No response

Steps to Reproduce

1. Configure Sentry automatically with Next.js with the wizard
2. Use hidden-source-map by setting the hideSourceMaps option in next.config.js

const moduleExports = {
  sentry: {
    hideSourceMaps: true,
  },
};

3. Run next dev to start Next.js in development mode

Expected Result

Run Next.js with Sentry without any warning.

Actual Result

Since the introduction of the next.config.js validation via ajv on version 12.2.3, the following warning is raised.

warn  - Invalid next.config.js options detected: 
[
  {
    "instancePath": "",
    "schemaPath": "#/additionalProperties",
    "keyword": "additionalProperties",
    "params": {
      "additionalProperty": "sentry"
    },
    "message": "must NOT have additional properties"
  }
]
