Boto3 Problem: "BucketName", must be one of: S3. Cannot move archives from Glacier to s3 bucket

Question

I'm using Boto3 to try to create an Inventory Retrieval Job from Glacier. Relevant part of my job retrieval dict looks like this:

```
job_params = {
            'Type': 'inventory-retrieval',
            'OutputLocation': {
                'BucketName': self.returnBucket,
            },
            'InventoryRetrievalParameters': {
                'StartDate': formatStart,
                'EndDate': formateEnd,
            },
        }
```
The error I get says" BucketName", must be one of: S3. The Boto3 Documents say that it's [supposed to be a string](https://boto3.amazonaws.com/v1/documentation/api/latest/reference/services/glacier.html#Glacier.Client.initiate_job), with the bucket name. I've tried both the bucket name and the ARN and they don't work.

I Tried created resource that I thought was the right approach:

```
s3_resource = boto3.resource('s3')
s3_bucket = s3_resource.Bucket('the bucket name')
```

but when the self.retrurnBucket = s3_bucket I still get the same error.

Answer

The doco page you linked to shows jobParameters contains:
```
        'OutputLocation': {
            'S3': {
                'BucketName': 'string',
```
Looks like you forgot the 'S3' bit.

Answer

Hello you have to use it like below:

```
jobParameters={
        'Type': 'inventory-retrieval',
        'Format': 'JSON',
        'OutputLocation': {
            'S3': {
                'BucketName': bucket_name,
                'Prefix': inventory_file_key
            }
        }
    }
```
