It looks like you’re using a much older version of the AWS SDK. In your

import

, you’re referencing

<http://github.com/pulumi/pulumi-aws/sdk/go/aws/ec2|github.com/pulumi/pulumi-aws/sdk/go/aws/ec2>

, but the example references v5 (

<http://github.com/pulumi/pulumi-aws/sdk/v5/go/aws/ec2|github.com/pulumi/pulumi-aws/sdk/v5/go/aws/ec2>

). You may want to update your imports and

go.mod

and see if that helps.
