Graphql error: did not yield content fragment

Hello,

I am using aem cloud sanbox environment.

I am using graphql to fetch content fragment. It is working perfectly on author instance but when I check on publish instance then getting this error in response:

{"errors":[{"message":"Exception while fetching data (/ourClientsReferenceByPath) : Path: '%2Fcontent%2Fdam%2Franosys-website%2Four-clients%2Fparent-fragment%2Fclients-homepage' did not yield a Content Fragment","locations":[{"line":2,"column":3}],"path":["ourClientsReferenceByPath"],"extensions":{"classification":"DataFetchingException"}}],"data":null}

Please help to provide the solution.
