Serverless-offline: Uncaught error: Cannot read property 'done' of undefined

[sagar-gavhane]

I'm using serverless-offline plugin for testing aws lambda functions locally. But when I'm trying to send a response back to the user with res.send() the method throws me below error.

Debug: internal, implementation, error 
    TypeError: Uncaught error: Cannot read property 'done' of undefined

Early response will be highly appreciated.

Looks like a duplicate of https://github.com/dherault/serverless-offline/issues/659 that was closed.

The cause is cleanup happening before asynchronous handler finishes executing

Have you tried this workaround https://github.com/dherault/serverless-offline/issues/661#issuecomment-493202885?

Reverting to [email protected] fixed this issue for me in the short term, same error found in 4.10.1,2,3

[corroded]

Same, although I reverted to 4.9 instead

[errawn]

I am encountering this also.

[dherault]

What about v4.10.4?

[sulaysumaria]

Seems to be fixed in v4.10.5. or maybe with serverless 1.43.0... I updated both today and error is gone.

Upgrading from 4.10.2 to 4.10.5 fixed the issue for me.
