Description: 

After upgrading erwin and Web Portal to 2018 R1, when publishing to Web Portal from erwin get error:

java.rmi.RemoteException: null: {"result":null,"error":{"errorCode":"INVALID_REPOSITORY_PATH","message":"Either /Published is not a valid configuration content or version path, or the configuration content does not have a version.","details":""}}

ERROR:The tool failed with error code ERROR_EXPORT

Solution:

It is because of the configuration path is different than in the previous version.

In the earlier version, the default was:

Repository configuration path = /Published

in Web Portal 2018 R1 the new path is:

Repository configuration path =/Configuration/Published

Please change Repository configuration path =/Configuration/Published to make it work.
