implementing Lambda Function Timeout When Accessing S3 with VPC Configuration
I'm updating my dependencies and I'm currently working with a timeout scenario with my AWS Lambda function that processes files from an S3 bucket... The Lambda function is configured to run within a VPC and has been allocated a timeout of 30 seconds. However, when it tries to access S3, it consistently times out after around 25 seconds, resulting in the following behavior message in the logs: `Task timed out after 25.00 seconds`. I've ensured that the Lambda function has the necessary IAM permissions to access S3, but the communication seems to be failing due to the VPC configuration. I've attempted to address this by creating a NAT Gateway in the public subnet to enable outbound internet access. My Lambda function is in a private subnet with a route table that directs internet traffic (0.0.0.0/0) to the NAT Gateway. Here's the relevant portion of my VPC setup: ```json { "Resources": { "MyNATGateway": { "Type": "AWS::EC2::NatGateway", "Properties": { "SubnetId": "subnet-abcdef123", "AllocationId": { "Fn::GetAtt": ["MyEIP", "AllocationId"] } } }, "MyRouteTable": { "Type": "AWS::EC2::RouteTable", "Properties": { "VpcId": "vpc-123456789", "Tags": [{ "Key": "Name", "Value": "MyRouteTable" }] } } } } ``` However, the question continues. I also checked the security group settings for the Lambda function and ensured that it allows outbound traffic. I've also tried increasing the timeout setting to see if that helps, but it still fails at around the same time. Is there something I'm missing in my VPC setup, or another configuration related to Lambda that could be causing this timeout? Any insights would be greatly appreciated. For reference, this is a production desktop app.
