User Registration lambda doesn't work

I deployed the User Registration lambda and found that is doesn't work.
The /user-registration endpoint returns error 502.
There is an error in the CloudWatch logs:

Unable to import module 'src-server/newLambda': Error
at Function.Module._resolveFilename (module.js:469:15)
at Function.Module._load (module.js:417:25)

It looks like the error occurs in /dist/modules/AggregateRepository.js:7:20)
This code is there: var _regenerator = require('babel-runtime/regenerator');
