ReportPortal return error when parallel execution

[billyjulius]

I am using Serenity with Cucumber, and ReportPortal return this error when run multiple cucumber runner in parallel. This happens sometimes and random (not all scenario, but random each run)

@billyjulius Unfortunately parallel mode isn't supported for now.

@Invictum Found the cause of this error, apparently it is caused by integration trying to post all the step of each DataDriven Scenario (Scenario Outline & Examples in Cucumber) and using its each step StartTime, meanwhile the parent test item started using StartTime of the LAST DataDriven Scenario.

Thanks for the investigation. Can you provide a simple and synthetic project for debug, so I will try to fix it?
