Add Lambda function to AWS AppSync Data Source?

Question

I am trying to follow this tutorial on the AWS Site.

I added the GraphQL Schema but then when I try to add the Lambda Function in the Data Sources I can't add it because the Function ARN field is disabled.

How do I add Lambda function to AWS AppSync?

Answer 1

The drop-down lets you select an AWS Lambda function from the region selected in the "Region" drop-down. If you don't see anything populated in the list, it usually means that no Lambda functions exist in that region.

Can you check if you have Lambda functions in SA-EAST-1?
