Unexpected token error with cdk deploy on an existing stack project (written in Java) #20678

ShubhamSrivastava93 · 2022-06-09T05:32:34Z

Describe the bug

Hi I've an existing stack project written in Java. So far I've been deploying it using cdk deploy command and it was working as expected but suddenly since yesterday (with no change) I started getting error regardless of what the CDK template is. I tried with node versions v14.17.6, v10.16.3 and v10.19.0 but no luck. I doubt if other cdk commands like synth would also work or not

Expected Behavior

cdk deploy should generate cft and deploy it to AWS, like it was doing so far

Current Behavior

Getting below error

Exception in thread "main" software.amazon.jsii.JsiiException: Child process exited unexpectedly!

Same issue here with Node 12 and CDK (Python) 2.27.0

Onkar-Kandalgaonkar · 2022-06-09T08:26:51Z

I am also getting the same error on local linux machine and also on jenkins pipeline.
Node v10.19.0, aws-cdk 1.132.0

mickael-caro-sonarsource · 2022-06-09T08:28:44Z

Bumping to Node 16 seems to have mitigated the issue.

aws/jsii#3589

solving the problem?

emmamoinat · 2022-06-09T14:52:13Z

Seeing the same issue just started today (09/06/2022) - had been running fine in node v 8 and v 12 before today.

zhangwenjia0326 · 2022-06-09T15:34:41Z

Experiencing the same issue. For now, I added "jsii == 1.59.0" in my requirement.txt, which temporarily fixed my issue. Open to better short term solution suggestions though while this is being fixed.

ShubhamSrivastava93 · 2022-06-09T19:19:09Z

Bumping to Node 16 seems to have mitigated the issue.

upgrading to node 16 worked but just wondering how a specific combination of cdk, node and other dependent libraries versions suddenly stopped working

peterwoodworth · 2022-06-09T23:20:53Z

We dropped support for node 12 in our latest JSII release https://github.com/aws/jsii/releases/tag/v1.60.0

Then released a hotfix because of the ?? issue aws/jsii#3588

This issue should be fixed?

emmamoinat · 2022-06-10T08:00:35Z

I tried both jsii at version 1.60.0 and 1.60.1 but sadly I am still seeing errors.

For me the error is coming when I call something like:
InstanceType("r5.4xlarge")

which is import software.amazon.awscdk.services.ec2.InstanceType

And it seems to fail here in JsiiRuntime:

        try {
            String responseLine = this.stdout.readLine();
            if (responseLine == null) {
                throw new JsiiException("Child process exited unexpectedly!");
            }
            final JsonNode response = JsiiObjectMapper.INSTANCE.readTree(responseLine);
            JsiiRuntime.notifyInspector(response, MessageInspector.MessageType.Response);
            return response;
        } catch (IOException e) {
            throw new JsiiException("Unable to read reply from jsii-runtime: " + e.toString(), e);
        }
    }

because responseLine is null.

This only happens on node 12 but I don't have the ability currently to update my pipeline to node 14 or 16 so need a fix.

Versions:
Now using node v12.8.0 (64-bit)
cdkVersion = "1.36.1"
jsiiVersion = "1.60.1"

ayachnes2 · 2022-06-10T14:06:51Z

@emmapatterson I am also using CDK with Java, and I'm using node 12.22.12 and CDK 1.130.0. I was in a similar situation as you except I tried downgrading the transient depdendency software.amazon.jsii:jsii-runtime:1.59.0, getting the following error message:

Exception in thread "main" software.amazon.jsii.JsiiException: Unexpected token '?'
jsii-kernel-PGFecQ/node_modules/constructs/lib/construct.js:501
        const nodeFactory = options.nodeFactory ?? { createNode: (host, nodeScope, nodeId) => new Node(host, nodeScope, nodeId) };

This was happening because of the transient dependency software.constructs:constructs:3.4.32, which is a breaking minor version change for node 12. Downgrading software.constructs:constructs:3.4.32 to software.constructs:constructs:3.4.31 fixed the issue.

So, in summary, I can confirm that the following works with node 12.22.12:

Downgrade software.amazon.jsii:jsii-runtime to 1.59.0
Downgrade software.constructs:constructs to 3.4.31

With a build system like gradle that looks something like:

configurations.all {
  resolutionStrategy {
    force 'software.amazon.jsii:jsii-runtime:1.59.0'
    force 'software.constructs:constructs:3.4.31'
  }
}

@ayachnes2 you are my hero.

kknd4eva · 2022-06-15T07:39:34Z

Can confirm that updating from NodeJS 12.x to 14.x resolved this issue for us. We have a CICD pipeline in Azure DevOps using CDK. This error only started occurring a few days ago.

@th3outcast Upgrading to latest version of node fixes error as optional chaining was introduced in Node 14.
