Description

Example

var batch = odataClient.CreateBatch();
batch.Create("Tests", new TestEntity { Name = "test"} );
await batch.ExecuteAsync(context.CancellationToken);

Error from OData Client

This operation is not supported for a relative URI.

Environment

• PanoramicData.OData.Client version: 10.0.47
• .NET version: .NET 10

Root Cause

Every batch operation has relative url. So we need add check if url IsAbsoluteUri in HttpMessageContent

private async Task<byte[]> BuildContentAsync()
	{
		var sb = new StringBuilder();
		// Request line: METHOD path HTTP/1.1
		// Below add check IsAbsoluteUri
		var requestUri = _request.RequestUri?.PathAndQuery ?? "/";.
	...
	}

Will need more that that unfortunately. It fails further down the content build when it tries to parse the host from the Url

		// Host header
		if (_request.RequestUri?.Host is not null)

It will need to pull the host from the baseurl from the options supplied to the client.

is there a workaround or an eta on this?

I fixed this bug in my fork of this project. You can fork it and build your own dll.
