Cannot select/view Lambda function when configuring AWS Lambda from AWS API Gateway web interface

Question

I am using AWS API Gateway and AWS Lambda. I am configuring the API gateway to integrate with a lambda function.

When I select the region that the lambda function is in, the lambda function is not visible on the list of available functions.

When I try and configure the integration, from the AWS API Gateway web interface, as an AWS service and I input the ARN number for the lambda function, I get an invalid ARN number. The number is correct.

Answer 1

I was facing the same problem. I could not find my lambda function in the drop down. Then I simply copy pasted my lambda function name and saved the api gateway. It worked for me. I think the text box for lambda function is somehow showing cached results.
