Google Cloud Composer - Unable to read remote log

[Paweł Lonca]

I'm trying to run my Airflow DAG on the Cloud Composer by Google (composer-1.16.4-airflow-1.10.15). Tasks can't be completed because Composer can't access log files. The error I get is as follows:

*** Unable to read remote log from gs://europe-west1-XXXXXXXXXXXXXXXX-bucket/logs/main_jira_dag/get_project_tasks_TBA/2021-05-19T08:02:32.739900+00:00/1.log *** 'NoneType' object has no attribute 'download' *** Log file does not exist: /home/airflow/gcs/logs/main_jira_dag/get_project_tasks_TBA/2021-05-19T08:02:32.739900+00:00/1.log *** Fetching from: http://airflow-worker-YYYYYYYYYYYY:<port>/log/main_jira_dag/get_project_tasks_TBA/2021-05-19T08:02:32.739900+00:00/1.log *** Failed to fetch log file from worker.

What should I do to enable Composer reading remote log files?
