pingzh commented on issue #6174: [AIRFLOW-5543] Fix tooltip disappears in tree and graph view URL: https://github.com/apache/airflow/pull/6174#issuecomment-534677865 @feng-tao we upgraded one of our clusters to `1.10.4` from `1.10.0`. We planned a downtime to do it as we noticed the payload of task sent to the queue was different between those airflow versions. so we cannot have two different airflow versions running. Not sure about your current airflow version in production. If you use `ElasticSearch` as your log backend, be sure to cherry pick this commit: https://github.com/apache/airflow/pull/6159/files
