Gets an exception Microsoft.Owin.Security.Authorization.WebApi.ResourceAuthorizeAttribute.IsAuthorized

[sid1260]

Hi David,
I have a .NetFramework 4.7 WebApi project. I had added the Microsoft.Owin.Security.Authorization.WebApi Nuget package.

In my StartUp,cs I have the following line
app.UseAuthorization(o =>
{
o.AddPolicy("contribute", policy => policy.RequireClaim(JwtClaimTypes.Role, "User.Contributor"));
});

In my controller I have added
[HttpGet]
[Route("{cargoShipmentGBID}/parties")]
[ResourceAuthorize(Policy = "contribute")]
[SwaggerResponse(HttpStatusCode.OK)]
[SwaggerResponse(HttpStatusCode.BadRequest,"Bad request")]
[SwaggerResponse(HttpStatusCode.NotFound,"Could not find a booking based on the ID")]
[SwaggerOperation(OperationId = "Get Booking Parties")]
public async Task RetrievePartyDetails(int cargoShipmentGBID)

However I end up with the following exception

{
"Message": "An error has occurred.",
"ExceptionMessage": "One or more errors occurred.",

}
}

Do you have any idea?

Thanks,

It is likely throwing on this line:

Owin-Authorization/src/Microsoft.Owin.Security.Authorization/AuthorizationHelper.cs

Line 88 in 38f2dd7

return _owinContextAccessor.Context.GetAuthorizationOptions();

That would only happen if the code was not running with the proper owin dependencies.
