Unable to Test Proxy Bridge for Document Service

Hi All,

We have build Proxy Bridge for Document Service. Based on the Help guide provide https://help.sap.com/viewer/b0cc1109d03c4dc299c215871eed8c42/Cloud/en-US/ed1c6732d4214c68846ab9813b9df943.html

But while access the Url for testing the service https://cmisproxy(subaccount).us3.hana.ondemand.com/cmisproxy/cmis/json

Getting below error message:

{"exception":"permissionDenied","message":"Config entry with unique name XXXXXXXX(Document RepositoryName ) is not allowed to be accessed"}

Need gudiance.

Thanks,

Chakravarti Gupta.
