Error Encountered During Migration for Applying Newly Supported Models to Existing Data

[Zherdev1996]

While attempting to apply newly supported models to existing data in Langfuse, I encountered an error during the migration process. The steps I followed are as per the documentation, but the migration fails with a MODULE_NOT_FOUND error. Additionally, my local imports from @langfuse/shared do not work. I need assistance to resolve the MODULE_NOT_FOUND error and get the local imports from @langfuse/shared to work correctly. Any guidance or steps to troubleshoot this issue would be greatly appreciated.

Environment:

Node.js version: v20.13.1
Pnpm vesrion: v8.15.8
Langfuse version: 2.42.0
OS: macOS

  const err = new Error(`Cannot find module '${request}'`);
              ^

Thanks for reporting this. Did you run pnpm i on the repo level?
