Lambda isBoundToVpc reports the wrong result #6261
Comments
I bumped into this same issue. As a workaround you can use this: private ensureLambda(props: SingletonFunctionProps): IFunction {
// TODO: Copy-pasted from CDK codebase until
// https://github.com/aws/aws-cdk/issues/6261 is fixed and we can
// use a proper SingletonFunction
const constructName =
(props.lambdaPurpose || 'SingletonLambda') + slugify(props.uuid);
const existing = cdk.Stack.of(this).node.tryFindChild(constructName);
if (existing) {
return existing as FunctionBase;
}
return new Function(cdk.Stack.of(this), constructName, props);
} |
@holmesjr, @JFox is this still an issue? I added the following to the test/integ.vpc-lambda.ts after deploying it a first time to get the IDs and it works as expected. const importedVpc = ec2.Vpc.fromVpcAttributes(stack, 'ImportedVPC', {
vpcId: 'vpc-0adcxxxxxxxxx274',
availabilityZones: ['us-east-2a', 'us-west-2b'],
privateSubnetIds: ['subnet-09ea9xxxxxxxxx330df', 'subnet-0xxxxxxxxxxxb2'],
});
const imported = new lambda.Function(stack, 'ImportedVpcMyLambda', {
code: new lambda.InlineCode('def main(event, context): pass'),
handler: 'index.main',
runtime: lambda.Runtime.PYTHON_3_6,
vpc: importedVpc,
});
imported.connections.securityGroups[0].addIngressRule(ec2.Peer.anyIpv6(), ec2.Port.udp(8888)); "ImportedVpcMyLambdaSecurityGroup76B6EDF3": {

[ResultSelector](https://docs.aws.amazon.com/step-functions/latest/dg/input-output-inputpath-params.html#input-output-resultselector) was added to ASL in August 2020 and is currently missing coverage in CDK. This change exposes a new `resultSelector` field to Task, Map, and Parallel state props. This is a JSON object that functions similarly to `Parameters` but where `$` refers to the state's raw result instead of the state input. This allows you to reshape the result without using extra Pass states. The implementation mimics what exists for Parameters. I'm not convinced we need extra types here. #### Example ```ts new tasks.LambdaInvoke(this, 'Invoke Handler', { lambdaFunction: fn, resultSelector: { lambdaOutput: sfn.JsonPath.stringAt('$.Payload'), invokeRequestId: sfn.JsonPath.stringAt('$.SdkResponseMetadata.RequestId'), staticValue: 'foo', }, }) ``` Which produces the following ASL: ```json { "Type": "Task", "Resource": "arn:aws:states:::lambda:invoke", "Parameters": { "FunctionName": ${functionName}, "Payload.$": "$" }, "ResultSelector": { "lambdaOutput.$": "$.Payload", "invokeRequestId.$": "$.SdkResponseMetadata.RequestId", "staticValue": "foo", }, "Next": ${nextState} } ``` ### Testing * Unit tests for Map, Task, and Parallel states to include `resultSelector` * Unit test with ResultSelector for `LambdaInvoke` state updated to include `resultSelector` * Updated LambdaInvoke integ test to use ResultSelector for one of the states. Executed state machine manually through the AWS console to ensure the example actually works too.

The way the current (lerna/yarn) build works includes the .ts file (as well as the .d.ts and .js) files in the asset bundle. Using the new `nozem` build (correctly) only includes the .d.ts and .js files, leading to a different asset hash. Since we don't care about the actual hash anyway, adding the ignore-assets pragma so this test can pass with either build tool. ---- *By submitting this pull request, I confirm that my contribution is made under the terms of the Apache-2.0 license* commit fb0977a Merge: 1effc9f df89694 Author: mergify[bot] <37929162+mergify[bot]@users.noreply.github.com> Date: Sat May 15 00:59:26 2021 +0000 chore(merge-back): 1.104.0 (#14708) See [CHANGELOG](https://github.com/aws/aws-cdk/blob/merge-back/1.104.0/CHANGELOG.md) commit df89694 Merge: 44d3383 1effc9f Author: mergify[bot] <37929162+mergify[bot]@users.noreply.github.com> Date: Sat May 15 00:33:23 2021 +0000 Merge branch 'master' into merge-back/1.104.0 commit 1effc9f Author: Hsing-Hui Hsu <[email protected]> Date: Fri May 14 15:18:14 2021 -0700 docs(ecs): add contributing guide (#14672) ---- *By submitting this pull request, I confirm that my contribution is made under the terms of the Apache-2.0 license* commit 44d3383 Merge: bc13a66 aaa0d05 Author: mergify[bot] <37929162+mergify[bot]@users.noreply.github.com> Date: Fri May 14 21:59:31 2021 +0000 chore(release): 1.104.0 (#14706) See [CHANGELOG](https://github.com/aws/aws-cdk/blob/bump/1.104.0/CHANGELOG.md) commit aaa0d05 Author: Neta Nir <[email protected]> Date: Fri May 14 14:33:52 2021 -0700 Update CHANGELOG.md commit 0328b03 Author: AWS CDK Team <[email protected]> Date: Fri May 14 21:30:07 2021 +0000 chore(release): 1.104.0 commit 348e11e Author: Madeline Kusters <[email protected]> Date: Fri May 14 14:27:19 2021 -0700 fix(ecs): Classes FargateService and Ec2Service have no defaultChild (#14691) * fix(ecs): Class FargateService has no defaultChild fixes #14665 * update unit tests commit 1a695e2 Merge: 84045fd d82de05 Author: Ben Chaimberg <[email protected]> Date: Fri May 14 11:45:50 2021 -0700 Merge branch 'master' into chaimber/lambda_perm_cond commit d82de05 Author: Bryan Pan <[email protected]> Date: Thu May 13 08:48:46 2021 -0700 chore(appsync): rds data source service integration with grantDataApi (#14671) Utilize the `grantDataApi` from RDS to complete service integration.

That code relied on the `aws-lambda` package being implicitly available, but that would cause `ts-node` to fail. Add an explicit import of it in the code - I checked the only difference in the generated JS code is the sourceMappingUrl, so it shouldn't make a difference at runtime, but allows `ts-node` to load that file successfully.

When creating a function connected to an imported VPC, the resulting template correctly assigns the subnets for the lambda, but the isBoundToVpc() method returns false and accessing the connections property of the lambda results in an error: "Only VPC-associated Lambda Functions have security groups to manage. Supply the "vpc" parameter when creating the Lambda, or "securityGroupId" when importing it."
The same happens when a new security group is attached.
