Getting 'Execution failed: Template evaluation timed out' from API Gateway

Question

I am load testing API Gateway using JMeter.

I am sending large HTTP POST requests from JMeter. All the requests being sent are identical and each request size is 7.6MB. But for some requests I am getting the following error `Execution failed: Template evaluation timed out`.

What is the cause of this error? and why am I getting it for only some requests? (even when the requests are identical)

Answer

If it is repetitive, I would urge you to check the Ctrail logs yourself for a common cause & then reach out to the Premium support for further triage. Contact the API gateway service support team using the AWS console and they can check out using the internal tools.

Answer

Hello,
Was this a one-off error OR is this condition/issue repetitive. Refer to the below document regarding API calls returning errors. However if this is repetitive, please check the Ctrail logs on your end to check on the reason/ Reach out to AWS Support for more details on the same.
