Cdktf deploy command returns 137 error code while running from node js script

[anilkaliya]

Expected Behavior

I have a script which has code to provision the stacks something like

async function execCommand(command: string): Promise<void> {
  return new Promise((resolve, reject) => {
    const childProcess = spawn(command, { shell: true });

    childProcess.stdout?.on("data", (data: any) => {
      process.stdout.write(data);
    });

    childProcess.stderr?.on("data", (data: any) => {
      process.stderr.write(data);
    });
    childProcess.on("error", (error: ExecException) => {
      console.error(`Error executing command '${command}': ${error.message}`);
      reject(error);
    });

    childProcess.on("exit", (code: any) => {
      if (code !== 0) {
        reject(new Error(`Command '${command}' exited with code ${code}`));
      } else {
        resolve();
      }
    });
  });
}`
async function provision(name: string) {
 
  const app = new App();
  new MyStack(app, name, name);
 new PgBackend(app, {
    connStr,
    schemaName: "public",
    skipSchemaCreation: true,
  });
  await app.synth();
  await execCommand(`cdktf deploy ${name} --auto-approve`);
}
//to run the parrallel deployments i am using promise.all
Promise.all([provision("y"),provision("x")]).then(() => console.log("All provision functions completed successfully."));`
`mystack.ts=======>
import { Construct } from "constructs";
import { AwsProvider } from "@cdktf/provider-aws/lib/provider";
import { Instance } from "@cdktf/provider-aws/lib/instance";
import { TerraformOutput, TerraformStack } from "cdktf";

export class MyStack extends TerraformStack {
  constructor(scope: Construct, name: string, workspace: string) {
    super(scope, name);

    // Define AWS provider
    const awsProvider = new AwsProvider(this, "aws", {
      region: "us-west-1",
    });

    // Define an EC2 instance resource
    const ec2Instance = new Instance(this, workspace, {
      ami: "ami-01456a894f71116f2",
      instanceType: "t2.micro",
      tags: {
        Name: workspace, // Replace with the desired name
      },
      provider: awsProvider,
    });

    new TerraformOutput(this, "ec2-instance-id", {
      value: ec2Instance.id,
    });
  }
}`

mystack is just one ec2 instance when i run this script it takes forever to complete and sometime returns the 137 error code

The reason i am writing this code is to test the parrallel deployments we have one configuration tool where we provisions the infra as per request(provision some ec2 instance for one client and s3 for other client) the cdktf deploy command is not streaming the logs back to node js process shell The script is just taking forever to finish(sometimes exits with 137 error code) is there something wrong the way i have used deploy command? or is it expected running script without the code of deploy works fine and completes immediately I want to build the app to run parrallel deployments/provisioning of resources on demand . is there a way for that with cdktf?

Actual Behavior

cdktf deploy command should execute and return no error while running it from node js script

Steps to Reproduce

create cdktf app with typescript template use aws provider run npx ts-node main.ts //to run the provisioning code

Versions

cdktf 0.20.3 language typescript

Exit code 137 hints towards an Out of Memory problem, could it be that your provisioning script takes up to much resources (together with cdktf)? I would suggest trying to split your provisioning and the cdktf application up to verify which one is the cause.
