Getting error HTTP/1.1 404 Could not determine Web Services Version from 'v2.0https:' while attempting to access the list of allowed values for a portfolio item's custom field. Able to hit the endpoint while attempting through the browser(Chrome) though.
e.g. below with Feature ID masked. https://rally1.rallydev.com/slm/webservice/v2.0/portfolioitem/feature/*******58600/c_IntakeLineofBusiness/AllowedValues
Why does this happen?
