If you see the same problem please raise a JIRA issue. Thanks Il giorno lun 29 apr 2019 alle ore 10:42 Remco Schoen <r.sch...@topdesk.com> ha scritto: Sorry, forgot to add that.

This OData feed requires authentication to get the metadata. As I have to refresh the Access Token for authenticating I can not add it to the configuration, but I'm using the CamelOlingo4.endpointHttpHeaders header for this. But when the component is retrieving the metadata it is ignoring the header and it is not able to authenticate. If I add the headers to the get metadata request it works. Is adding the headers the solution or is there another approach? Kind regards, Remco Schoen
