Info about the New /api route.
Is /api
hard coded into the [Route] path? as it shouldn’t be registered if your App is hosted on a custom path.
Can be changed with:
ConfigurePlugin<PredefinedRoutesFeature>(feature =>
feature.JsonApiRoute = "/custom/{Request}");
Or prevented from being registered with:
ConfigurePlugin<PredefinedRoutesFeature>(feature => feature.JsonApiRoute = null);
