Hi folks. I'm trying to use the S3 block to upload a file, however the resulting `content-type` on the uploaded file is always `binary/octet-stream`
```    s3bucket: S3 = S3.load("default")
    with open(local_path, "rb") as f:
        s3bucket.write_path(to_path, f.read())```
Does anyone have a pointer on how to set the metadata on upload? <@ULVA73B9P> ?

The built-in `S3` block has limits since it's built on top of `fsspec`. In the `prefect-aws`<https://github.com/PrefectHQ/prefect-aws| collection>, we have an <https://prefecthq.github.io/prefect-aws/s3/#prefect_aws.s3.S3Bucket|S3Bucket block> with an <https://prefecthq.github.io/prefect-aws/s3/#prefect_aws.s3.S3Bucket.upload_from_file_object|upload_from_file_object> method I think you could use here.

It has a `**kwargs` param you could use to pass metadata to the underlying boto3 library via ExtraArgs.

Awesome, thanks for the tip <@U03SXGWL1K4>

This works well. Thanks again. If anyone runs into this in future, here's some code:
```def upload_html(s3bucket: S3Bucket, html: str):
    with BytesIO() as f:
        f.write(html.encode())
        f.seek(0)
        s3bucket.upload_from_file_object(f, "analysis/index.html", ExtraArgs={
            "CacheControl": "no-cache",
            "ContentType": "text/html"
        })```


You're welcome, Mark! I'm happy it worked well. 

And thanks for sharing your code!
