AsyncAPI.NET isn't able to load external file #20
Description
Describe the bug
When I set the ReferenceResolution as ReferenceResolutionSetting.ResolveAllReferences and the message payload is referencing an external file, that file is not loaded
To Reproduce
Having an AsyncAPI V3 where the message payload is an external file and mark to resolve all references
var path = Path.Combine(Environment.CurrentDirectory, "V3_TestData", "AsyncApiSchema_MessageInDiffFile.yml");
var reader = new AsyncApiStreamReader(new AsyncApiReaderSettings
{
ReferenceResolution = ReferenceResolutionSetting.ResolveAllReferences,
});
var doc = reader.Read(File.OpenRead(path), out var diag);
Assert.IsEmpty(diag.Errors);Error:
Something went wrong trying to fetch './AsyncApiSchema_MessagePayload.yml. Could not find file '<READACT>\AsyncAPI.NET\test\ByteBard.AsyncAPI.Tests\bin\Debug\net8.0\AsyncApiSchema_MessagePayload.yml'.'Expected behaviour
The diagnostic should be empty

Oh snap! I'll look into it when I get back near a pc. Thanks you for reporting this.

I was wrong in my first assumption. you never hit the switch case. the uri is relative, and thus throws on the
.Schemecall in the switch. I've added a PR to fix it.VisualBean commentedon Oct 25, 2025
Would you like the ability to provide a baseUri for relative uris to be resolved against? or just resolve against the current working dir?
