Maybe I don't quite follow this, but I am using Ansible 2.7.6, and when I trigger an error on a task that has ignore_errors: true, I am still getting output from the debugger.

ie.

TASK [Find the user_id for gomer] ********************************************************************************************************************************************************************************************************
fatal: [nagios]: FAILED! => {"msg": "The task includes an option with an undefined variable. The error was: No first item, sequence was empty.\n\nThe error appears to have been in '/etc/ansible/role/purge_user/tasks/sample.yml': line 10, column 7, but may\nbe elsewhere in the file depending on the exact syntax problem.\n\nThe offending line appears to be:\n\n\n    - name: \"Find the user_id for {{ user }}\"\n      ^ here\nWe could be wrong, but this one looks like it might be an issue with\nmissing quotes.  Always quote template expression brackets when they\nstart a value. For instance:\n\n    with_items:\n      - {{ foo }}\n\nShould be written as:\n\n    with_items:\n      - \"{{ foo }}\"\n"}
