ERR_IPC_CHANNEL_CLOSED when autoMerge set to true.

[kpmck]

I have an Angular Nx project with Cypress. When I did not set autoMerge, the tests ran and were all reported to my instance of ReportPortal.

Once I switched to autoMerge, the first spec file ran successfully, and the second (and subsequent) spec files failed out with the ERR_IPC_CHANNEL_CLOSED failure, causing only the first spec file to run.

I was able to get the autoMerge to run successfully a handful of times, but once any change was made to the Cypress.json file, I was not able to get it to run again.

I have included a repo where this can be reproduced: https://github.com/kpmck/angular-nx-cypress-reportportal

Steps to reproduce:

1. open solution in VS Code
2. run npm i to install packages
3. add your ReportPortal details in the cypress.json file
4. run ng e2e to execute e2e tests

Cypress: 4.12.1 (I have also tried 5.4.0 and 4.1.0)
Node: 8.9.5
reportportal/agent-js-cypress: 5.0.1

The Project-Repo doesn't exist anymore.
Have you found a solution?

@kpmck hello. Have you found the solution?

[brabenetz]

@AM1988 I have done the following: #64 (comment)
Maybe there is something in it for you.

[AM1988]

@brabenetz thank you, will try this. And could you please share the info about how your cypress/plugins/index.js look like?
