Solve CDK recursing asset staging output ENAMETOOLONG error

Question

When deploying an aws CDK project, I am intermittently faced with an error containing the following text:
*Error: ENAMETOOLONG: name too long, copyfile '/opt/app/deploy-project/cdk/cdk.out/asset.549cca69f33e5b267d9a73aff143ef2ac7d7887e7d6fb24186e7c469b1f491ae/deploy-project/cdk/cdk.out/[repeating]*
It shows a recursion on one of the asset folders and it finally times out after 20 minutes.
I have tried some of the solutions I read about in the aws CDK GitHub issues:
1. add a .dockerignore file to the root of the project with the contents: cdk*
2. add an exclude property to the DockerImageAsset method:
```
image = ecr_assets.DockerImageAsset(self, 'DeployDockerImage',
                                            directory=os.path.abspath('../../'),
                                            file="deploy-project.Dockerfile",
                                            exclude=["cdk"]
                                            )
```
But none of these things have worked.  I also should mention that I am using aws-cdk-lib 2.69.0

Hello

By reviewing the GitHub issue and the code snippet provided, it appears there may be issues in the steps followed for the accepted solutions.

So, can you try the following approach described in the issue:

Excluding cdk.out in asset object instead of cdk

```

`: image = ecr_assets.DockerImageAsset(self, 'DeployDockerImage',
                                            ..
                                            exclude=['cdk.out']   //  you are excluding cdk
                                            )`
```

Alternative, the most popular solution suggests:

1. )added cdk* to .dockerignore to get it working (which you have  already done)
2. ) making sure check cdk.json, it should contain:

```
{
  "context": {
    "@aws-cdk/aws-ecr-assets:dockerIgnoreSupport": true
  }
}
```

If not specified as true .dockerignore is ignored
