Express plugin not working after v2.7.0 upgrade

[susannakosic]

Hi, I am having a hard time trying to upgrade dd-trace to newer versions.
I explained the issue I m facing in here as it seems the same bug as #2124, although in this case plugins are enabled (default).

Expected behaviour
Express plugin loads and express.request object is available on traces.

Actual behaviour
Express plugin does not load. Only separate express.middleware objects can be seen on traces.

Steps to reproduce

1. Clone dd-trace-upgrade-external repo.
2. run yarn install, yarn start and curl --location 'http://localhost:4000/documents'
3. Observe trace object contains express.request
4. run yarn add dd-trace@2.7.0, or any other 2.x upgrade
5. run yarn start and curl --location 'http://localhost:4000/documents'
6. Observe trace object no longer contains express.request

Environment

• Operation system: MacOs Ventura 13.4.1 (22F82)
• Node.js version: lts/gallium
• Tracer version: on upgrade 2.6.0>2.7.0
• Relevant library versions: express@4.18.2, serverless@3.24.1
