Research direction

Clone the linked enhancedev-fastify reproduction, run pnpm install, and compare pnpm dev with pnpm start. Trace where req.session is expected by the Fastify integration and determine why it is undefined in the start configuration; done means the reproduced application starts and accesses the session without the reported error.

Written by the indexing model from the issue text.

Description

During development (with sandbox) everything works, but when I would like to deploy with Fastify, the req.session is not available.

"statusCode": 500,
"error": "Internal Server Error",
"message": "Cannot destructure property '_idx' of 'req.session' as it is undefined."
}

Reproduce:

  • Clone this repository.
  • pnpm install
  • Test if it's working with pnpm dev -> Yes it will.
  • Test if it's working with pnpm start -> Nope.

Let me know if you need any further information.
