Dear all,
I’m glad to be a new user on Appgyver 
I am currently discovering the tool, I was able to perform the basic tutorials from SAP and Appgyver but when I try to pull data from an ODATA service located on a SAP Backend system (on premise), then the system sends me this error message: The entered URL is not recognized as a valid OData service metadata
Error 405 : Not allowed
As you can see on the screenshot, I have set up basic authentifications. When I test the URL on my browser, i am able to retrieve the metadata. When I go on transaction /IWFND/ERROR_LOG, I don’t have any error.
As you can see I am dealing with an HTTPS request with the good port associated.
Did I miss any set up in order to authorize the connection? Does this scenario (direct connection between Appgyver and on premise SAP) is supported?
Sorry I am more a functional guy, not so technical in those cases…
If you have any clue, don’t hesitate to share please:)
Have a good day all.
