Cannot find file cdk.Dockerfile when using AWS CDK #3440

Bug Description

Hi I tried to run AWS CDK on AWS cloud9 and my laptop (Mac book) for deploying Langflow onto AWS, but cdk bootstrap raises the error.

Error: Cannot find file at /Users/masaki/github/langflow/cdk.Dockerfile
    at new DockerImageAsset (/Users/masaki/github/langflow/scripts/aws/node_modules/aws-cdk-lib/aws-ecr-assets/lib/image-asset.js:1:2174)
    at new EcrRepository (/Users/masaki/github/langflow/scripts/aws/lib/construct/ecr.ts:40:37)
    at new LangflowAppStack (/Users/masaki/github/langflow/scripts/aws/lib/cdk-stack.ts:36:38)
    at Object.<anonymous> (/Users/masaki/github/langflow/scripts/aws/bin/cdk.ts:8:1)
    at Module._compile (node:internal/modules/cjs/loader:1546:14)
    at Module.m._compile (/Users/masaki/github/langflow/scripts/aws/node_modules/ts-node/src/index.ts:1618:23)
    at Module._extensions..js (node:internal/modules/cjs/loader:1691:10)
    at Object.require.extensions.<computed> [as .ts] (/Users/masaki/github/langflow/scripts/aws/node_modules/ts-node/src/index.ts:1621:12)
    at Module.load (node:internal/modules/cjs/loader:1317:32)
    at Function.Module._load (node:internal/modules/cjs/loader:1127:12)

This says ecr.ts does not find langflow/cdk.Dockerfile and we can find the file atlangflow/docker/cdk.Dockerfile in this repo. Thus, the following fix on the line may be needed. https://github.com/langflow-ai/langflow/blob/main/scripts/aws/lib/construct/ecr.ts#L22

const backendPath = path.join(__dirname, "../../../../../", "langflow")

should be 

const backendPath = path.join(__dirname, "../../../../", "docker")

The fix works for me. Could you check my suggestion?

Reproduction

Following the steps in this readme, we will see the error when running cdk bootstrap. https://github.com/langflow-ai/langflow/tree/main/scripts/aws

Expected behavior

Complete cdk bootstrap without errors.

Hey @harusametime! I'm here to help you with any bugs, questions, or contributions. Let's tackle this issue together!

Your suggestion to change the path in ecr.ts from:

const backendPath = path.join(__dirname, "../../../../../", "langflow")

to:

const backendPath = path.join(__dirname, "../../../../", "docker")

is correct. This adjustment correctly points to the langflow/docker/cdk.Dockerfile, resolving the issue when running cdk bootstrap [1].
