AWS Lambda has recently extended the capability to track the current state of a function through its lifecycle. In this post AWS wrote: “We’re extending the General Update from September 30 2021 to December 5 2021. The End of Delayed Update date is now also changed to December 6 2021.” With this change, all users of AWS Lambda need to update their AWS SDK-based automation workflows. How would it affect OpenRules-based decision services deployed as AWS Lambdas?

If you deployed your OpenRules-based decision model as an AWS Lambda function, it will continue to work without changes. However, if you want to make changes in the decision model and re-deploy you may receive an error like this one: “The operation cannot be performed at this time.” To resolve this issue, on December 5 we provided an emergency patch to the OpenRules Decision Manager Release 8.4.2 and you need to update your release. Contact support@openrules.com if there are any issues.

As an alternative, instead of the simple “deployLambda.bat” you may use “package.bat” to pack your decision model as a jar-file and use the default AWS Lambda deployment GUI by uploading this file through AWS API Gateway.
