We've upgraded our WSO2 API Manager from version 2.1 to 2.6. We are using all in one deployment. After migration we have a very confusing situation. In a Store I see no published API's until I log in to the Store. Then, in a Publisher app I see all the API's in a published state, but when I edit any of them I am not able to save it or go to Implement or Manage tab - always a 'null' error appears. A stack trace from wso2carbon.log for such cases is below. I have no idea what is going wrong and any help would be very appreciated.
