ReferenceError when running Next.js app with AppMap

[brentbaum]

Hello AppMap team,

I encountered an issue while trying to run my Next.js application with AppMap. When executing the command npx appmap-node npx next start, I received the following error:

⨯ ReferenceError: Cannot access 'default' before initialization
at Object.default (webpack-internal:///./node_modules/next/dist/client/router.js:21:9)

It seems that there might be an incompatibility between AppMap and my Next.js project, specifically related to the router initialization.

Environment:

• Next.js version: 14.2.3
• AppMap version: 2.24.3
• Node.js version: 18.17.1

Thank you!
