AddOnlyPublishedPaths is not compatible with Routing transforms

[aurelienhayet]

Hi,

In the ReverseProxyDocumentFilter class, at line 151, you search the pathKey (which is the target endpoint one) in the publishedRoutes dictionary (which is created from the routes configuration Path property, in other words the source endpoint):

var pathKey = $"{swagger.PrefixPath}{path.Key}";
if (!publishedRoutes.ContainsKey(pathKey))
{
    continue;
}

Logically, it cannot match.
This leads to unwanted filtering of all transformated paths.

Regards,

Aurélien

@aurelienhayet Hi! Thank you for your issue. You're right. We need to improve our library to interpret YARP transforms. For now, you need to avoid significant path transformations when using AddOnlyPublishedPaths flag. Use "PathPattern": "{**catch-all}" or "PathRemovePrefix": "/proxy-app1". It works.
