(aws-lambda-nodejs): Uploaded file must be a non-empty zip

What is the problem?

I updated lambda function dependancies and deploying the lambda function but it fails with following error.

I also have another api under the same project and I updated its lambda function dependancies and it was deployed successfully.

Both api’s and its lambda functions are almost identical to each other. However only one gets deployed and another one doesn’t.

I deleted the cdk.out folder and tried to deploy again and it fails with same error each time.

Reproduction Steps

I have simple lambda function that I am trying to deploy as follows

import { NodejsFunction } from 'aws-cdk-lib/aws-lambda-nodejs';
import { Architecture, Code, Function, Runtime } from 'aws-cdk-lib/aws-lambda';

const authFn = new NodejsFunction(this, 'authNodeJs', {
      runtime: Runtime.NODEJS_14_X,
      entry: `${__dirname}/../auth/index.ts`,
      handler: 'auth',
      architecture: Architecture.ARM_64,
      memorySize: 1024,
      environment: {
        CLIENT_ID: appClientID
      }
    })

const auth1Fn = new Function(this, 'authGolang', {
      runtime: Runtime.GO_1_X,
      code: Code.fromAsset(`${__dirname}/../auth-1/`, {
        bundling: {
          image: Runtime.GO_1_X.bundlingImage,
          user: 'root',
          command: [
            'bash', '-c', [
              'cd /asset-input',
              'go build -o main main.go',
              'mv /asset-input/main /asset-output/'
            ].join(' && ')
          ]
        }
      }),
      handler: 'main',
      memorySize: 512,
      environment: {
        CLIENT_ID: appClientID
      }
    })

What did you expect to happen?

I expected it to deploy all of my lambda functions.

What actually happened?

I also get this error message when I run cdk deploy then cancel it using CTRL + C during the bundling stage.

When I try to redeploy, it appears to bundle everything again but during the CloudFormation deployment, this error message is shown and fails to deploy.

If I redeploy again, it bundles everything up and then deploys successfully.

It appears as though the second bundling attempt isn’t successful?

Got this error message when upgrading aws-cdk-lib version from 2.31.0 to 2.32.0.
