Generate dbt documentation from Google Cloud Composer

Question

I have a dbt project running on Cloud Composer and all my models and snapshots are running sucessfully.

I'm having trouble generating the documentation once all the processing is finished.

The integration between dbt and cloud composer is done via airflow-dbt and I have setup a task for the DbtDocsGenerateOperator. The DAG actually runs fine, and I can see in the log that the catalog.json file is being written to the target folder in the correspondent cloud bucket, but the file is not there.

Doing some investigation on the GCP logging, I've notice that there's a process called gcs-syncd that is apparently removing the file.

Wondering if anyone has had success in this integration before and was able to generate the dbt docs from cloud composer?

{
    insertId: "**********"
    labels: {2}
    logName: "************/logs/gcs-syncd"
    receiveTimestamp: "****-**-****:**:33.621914158*"
    resource: {2}
    severity: "INFO"
    textPayload: "Removing file:///home/airflow/gcs/dags/target/catalog.json"
    timestamp: "****-**-****:**:28.220171689Z"
}

Followed by this error message:

{
    insertId: "rdvl8sfx903ai0y8"
    labels: {
    compute.googleapis.com/resource_name: "***************"
    k8s-pod/config_id: "************************"
    k8s-pod/pod-template-hash: "*************"
    k8s-pod/run: "airflow-worker"
}
logName: "************/logs/stderr"
receiveTimestamp: "****-**-****:**:28.921706522Z"
resource: {

}
severity: "ERROR"
textPayload: "Removing file:///home/airflow/gcs/dags/target/catalog.json"
timestamp: "****-**-****:**:28.220171689Z"
}

The airflow log doesn't show me any errors at all, and the process succeeds with the message:
