Job jenkins gives error 137 and fails after ng build --aot from angular application

Being trying to automatize the run of the e2e tests from my angular app in jenkins. The tests are handled thanks to the Cypress framework. The problem is that the jenkins job fails before the tests are even called, so my guess is that there is something wrong with my angular config.

When I run the same instructions from jenkins locally, I am able to build my app, and run my tests without any problem.

I found a possible solution which is changing the target": "es2015", to es5, but after doing that, I got lots of errors.

Here's the some of the output message in jenkins:

15:26:35 Run `npm audit` for details.
