GitHub user NewtonChutney edited a discussion: task1.output.concat(task2) not compatible with NoneType
Hello there! We have 3 report generation tasks and a file-transfer task after all report tasks are completed. The report generation tasks' outputs are the reports' file paths. But in case one of the extracts fail, we still send the rest of the reports and we use TriggerRule.ALL_DONE. But, when migrating to use the new `task1.output.zip(task2.output, task3.output)` syntax, i face this issue: > ValueError: XCom zip expects sequence or dict, not NoneType I don't think `task2.output.map()` will help in this scenario.. What else are my options that solely rely on this new syntax, without jinja?
