az monitor log-analytics query -w $WORKSPACE_ID \
    --analytics-query "ContainerAppConsoleLogs_CL | where ContainerAppName_s == '$CONTAINER_APP_NAME' and Log_s contains 'error' | project TimeGenerated, Log_s | order by TimeGenerated desc | take 20" \
    -o table
Log_s                                                                     TableName      TimeGenerated
