Context Separation Issue

[timon-roenisch-cpi]

Describe the bug

Contexts are not kept separated after upgrading graphql-modules to any version above 2.2.0. In earlier versions, each request context remains distinct. Upgrading causes the context being overwritten by a parallel request.

To Reproduce
Steps to reproduce the behavior:

1. Implement a resolver that executes additional functionality which takes some time. Can be simulated with a timeout.
2. Call an injected service which uses the @ExecutionContext() and returns an identifiable value from that context.
3. Send at least two parallel requests.

Expected behavior

The contexts should remain the same during the whole runtime of the resolving function.

Environment:

• "graphql-modules": "2.2.1" and above, including 3.0.0
• NodeJS: 22.14
