We need to make sure that

• Travis CI tests are passing
• AWS codebuild is executed with no error

This is also related to #900, #901, #902, #903 and #904

More info - current status:

When upgrading to node js 12:

• Travis CI passes See The Travis build.
• ASW Codebuild fails See the AWS Codebuild log.
