Deploy lambda function on aws-pulumi

Question

I'm trying to deploy a lambda Function on my AWS account, that zips a file that is uploaded into "lambda-bucket-in" onto a bucket "lambda-bucket-out". The example I'm trying to follow is this one, specifically the second way (the first does its job properly).

My pulumi code is the following one:

import * as aws from "@pulumi/aws";
import * as pulumi from "@pulumi/pulumi";


const tpsReports = new aws.s3.Bucket("lambda-bucket-in");
const tpsZips = new aws.s3.Bucket("lambda-bucket-out");


// First, create some IAM machinery:
const zipFuncRole = new aws.iam.Role("zipTpsReportsFuncRole", {
    assumeRolePolicy: {
       Version: "2012-10-17",
       Statement: [{
          Action: "sts:AssumeRole",
          Principal: {
             Service: "lambda.amazonaws.com",
          },
          Effect: "Allow",
          Sid: "",
       }],
    },
 });
 new aws.iam.RolePolicyAttachment("zipTpsReportsFuncRoleAttach", {
    role: zipFuncRole,
    policyArn: aws.iam.ManagedPolicy.AWSLambdaExecute,
 });
 
 // Next, create the Lambda function itself:
 const zipFunc = new aws.lambda.Function("zipTpsReportsFunc", {
    environment: {
       variables: {
          "TPS_ZIP_BUCKET": tpsZips.bucket,
       },
    },
    code: new pulumi.asset.AssetArchive({
       ".": new pulumi.asset.FileArchive("app"),
    }),
    runtime: "nodejs12.x",
    role: zipFuncRole.arn,
 });
 
 // Finally, register the Lambda to fire when a new TPS report arrives:
 tpsReports.onObjectCreated("zipTpsReports", zipFunc);

While "app" file, with the lambda function is:

   const AdmZip = require("adm-zip");
   const s3 = new aws.sdk.S3();
   for (const rec of e.Records || []) {
      const zip = new AdmZip();
      const [ buck, key ] = [ rec.s3.bucket.name, rec.s3.object.key ];
      console.log(`Zipping ${buck}/${key} into ${tpsZips.bucket.get()}/${key}.zip`);
      const data = await s3.getObject({ Bucket: buck, Key: key }).promise);
      zip.addFile(key, data.Body);
      await s3.putObject({
         Bucket: tpsZips.bucket.get(),
         Key: `${key}.zip`,
         Body: zip.toBuffer(),
      }).promise();
   }

While running pulumi with the command pulumi up --yes, and after inserting the password, it returns:

Does anyone know how to fix this issue, and what does it stand for? Thank you for your help.

I suspect that the problem can be in code section of Lambda function, probably you need to use absolute path for the "app" directory. You can try this change replace code with this.

new pulumi.asset.AssetArchive({
   ".": new pulumi.asset.FileArchive(path.join(__dirname, "app")),
}),

and import path at start of the script:

import * as path from "path";
