Ooops error running any DAG

[BigDataBrasil]

Hey guys,

I´m trying to run a DAG but it´s showing the following error. It was working for months until yesterday. Does anyone know what might be happening? I´m sending the logs below.

I´m running Airflow in Docker with Kubernetes.

Kubectl version:

Client Version: version.Info{Major:"1", Minor:"15", GitVersion:"v1.15.2", GitCommit:"f6278300bebbb750328ac16ee6dd3aa7d3549568", GitTreeState:"clean", BuildDate:"2019-08-05T09:23:26Z", GoVersion:"go1.12.5", Compiler:"gc", Platform:"linux/amd64"}

The error log suggest:
sqlalchemy.exc.IntegrityError: (sqlite3.IntegrityError) NOT NULL constraint failed: task_instance.pool
what airflow version are you running? Can you please add reproduce steps?
