  • I am also facing this error from yesterday. Seems like some change in AWS is causing this error. – eldos Nov 24 '21 at 07:36
  • I feel if we add `time.sleep` here, it should fix the issue https://github.com/ib-devs/Zappa/blob/apigateway_stages_multiple_routes_support/zappa/cli.py#L845 – eldos Nov 24 '21 at 07:42
  • I can fix this problem upgrade zappa version and change python version inside virtual enviroment to 3.8 – daniel____ Nov 28 '21 at 22:44

I would add a more sophisticated solution what mentioned LiriB earlier. Use the aws lambda cli which has the function-updated command (documentation).

Example: aws lambda wait function-updated --function-name "$FN_NAME"

This command will wait until the function is updated. In case it is not upated in 5 minutes, it will stop the execution.

You should wait for function code update to complete before proceeding with update of function configuration. Inserting the following shell script between the steps can keep the process waiting:

STATE=$(aws lambda get-function --function-name "$FN_NAME" --query 'Configuration.LastUpdateStatus' --output text)
while [[ "$STATE" == "InProgress" ]]
do
    echo "sleep 5sec ...."
    sleep 5s
    STATE=$(aws lambda get-function --function-name "$FN_NAME" --query 'Configuration.LastUpdateStatus' --output text)
    echo $STATE
done

Add to your zappa_settings.json:

"lambda_description": "aws:states:opt-out"

Zappa issue about it
