Cloudflare R2 S3 Compatibility help

I'm getting an error trying to get Sleet to init.

> .\Sleet.exe init --source library --verbose

I noticed the Pushing line entry has the path doubled up, however the Failed to upload line does not.

I'm using a Cloudflare R2 bucket, which has S3 compatibility and have verified I can connect and upload to the bucket via an S3 client.

In my sleet.json file I've got

• "path" variable set to my public custom domain, I suspect this might be where I'm falling over. If I try to set it to anything other than a full valid URI I get errors [System.UriFormatException] Invalid URI: The URI is empty. or [System.UriFormatException] Invalid URI: The format of the URI could not be determined.

@jcerecke try putting the public url under baseURI instead, path should be the bucket uri.

If that doesn't work please share an example sleet.json config that repros this.

No change. Do I even need the public URL in my config? I'm new to s3 to still trying to work out the basics.

{
  "sources": [
    {
      "name": "library",
      "type": "s3",
      "path": "https://<account ID>.r2.cloudflarestorage.com/library/",
      "baseURI": "https://library.example.com",
      "bucketName": "library",
      "serviceURL": "https://<account ID>.r2.cloudflarestorage.com/",
      "accessKeyId": "<redacted>",
      "secretAccessKey": "<redacted>"
    }
  ]
}

The baseURI/public url will be written to the json files, and that is what NuGet will then reference and try to read. So if you are hosting the bucket via something else you might need to write the files under that public url.

I would try removing the baseURI and the path properties from your config, see if that resolves the issue.

There is likely a bug somewhere in that it isn't expecting multiple properties to be set and so it is duplicating the paths.

Somehow I completely missed the section in the docs on using s3 compatible storage which includes an additional key that I had missed:

"disablePayloadSigning": false, // set to true if SigV4 is not supported by provider (such as Cloudflare R2)

Once I added that and set it to true it started working. Thanks for the help.

A doc is needed specifically for Sleet feeds on Cloudflare, it is becoming a popular option. It is obvious how to make it work from the current docs.
