I signed CLA after the merge request opened, is there any problem with CLA synchronization?

[isikhi]

I signed CLA a few times but could not completed this step idk why. I signed with github related email but i am not sure why it is not completed :thinking: Any help ? Or maybe you can cherry pick my changes these are a few little changes.

Hi @isikhi

about the CLA you may want to send an email to [email protected]

also I want to ask if you checked my last comment on #3630. The sample you provided has the require('express') before the require('elastic-apm-node').start(...)so that agent is too late to instrument the express framework.

Please confirm you have tested your sample with require('elastic-apm-node').start(...) at the top of the file and see the same behavior. Thanks!
