Facing some issues with AWS EventBridge Application

Question

Hi,

I am trying out the sample EventBridge application at this [URL](https://docs.aws.amazon.com/eventbridge/latest/userguide/eb-tutorial-get-started.html) I have managed to work this out to an extent on WSL with Ubuntu. Everything has been smooth until I actually deploy the stack using

```
sam deploy --guided
```
I have provided the required responses to the above command. I am getting an error. The required resources are not created and deployed. These are probably being rolled back due to the error

For reference I have provided the response from the above command, below
 
```
Configuring SAM deploy

Looking for config file [samconfig.toml] :  Found
        Reading default arguments  :  Success

Setting default arguments for 'sam deploy'
        =========================================
        Stack Name [Test]: Test
        AWS Region [us-east-1]:
        #Shows you resources changes to be deployed and require a 'Y' to initiate deploy
        Confirm changes before deploy [Y/n]: Y
        #SAM needs permission to be able to create roles to connect to the resources in your template
        Allow SAM CLI IAM role creation [Y/n]: Y
        #Preserves the state of previously provisioned resources when an operation fails
        Disable rollback [y/N]: N
        Save arguments to configuration file [Y/n]: Y
        SAM configuration file [samconfig.toml]:
        SAM configuration environment [default]:

Looking for resources needed for deployment:

Managed S3 bucket: aws-sam-cli-managed-default-samclisourcebucket-22dlzjzisaai
        A different default S3 bucket can be set in samconfig.toml and auto resolution of buckets turned off by setting resolve_s3=False

Saved arguments to config file
        Running 'sam deploy' for future deployments will use the parameters saved above.
        The above parameters can be changed by modifying samconfig.toml

Error: Unable to upload artifact atmProducer/ referenced by CodeUri parameter of atmProducerFn resource.

S3 Bucket does not exist.
```
Just for information, the error mention a missing S3 bucket. That's one thing I haven't been able to understand. But I am sure there is something I have missed out. Apologies in advance.

Could anyone guide me in the right direction?

Thanks

> Looking for config file [samconfig.toml] : Found

You already have samconfig.toml. Did you download and use the working code?
(URL could not be verified)

Usually, the first time you do `sam deploy --guided`, you create an S3 bucket and set the created S3 information in `samconfig.toml`.

If this is your first time deploying, you can delete `samconfig.toml` and try it and see.

Answer

When you first run the SAM cli, it creates a CloudFormation stack called aws-sam-cli-managed-stack which creates an S3 bucket thats used to managed SAM deployments (unless you specify another S3 bucket) , and   a bucket policy.  It seems that this bucket has been deleted. You can verify this by looking at the outputs of the managed stack and verifying that the bucket name listed under `SourceBucket` still exists.  To fix this, you can delete the aws-sam-cli-managed-stack and run `sam deploy --guided`  again.
