I am following that approach, however it is not working. This approach was working in previous versions, for example Pega 7.3, but trying to do the same in Pega 8.2 with new URL configuration it is not possible.
This is the error message that I got:
Step Status Info
The service URL =D_LoadEnvParamREST.pxPages(BuildingsPOST).EndPointURL does not start with a protocol and hostname
Please look into the referenced data page on the clipboard to see the values of the EndPointURL. Is it valid? If the data page is loaded during server startup, maybe try the node restart to see if that fixes the issue. Otherwise, reload the datapage, does it make any difference?
