Custom Conversion Stats are not available for some events?

Hi, I am getting below error message while accessing the custom conversions graph API. { "error":{ "message": "(#200) Cannot access an object not managed by the business owning this app.", "type":"OAuthException", "code":200, "fbtrace_id":"AGw9gisVrG3m5dNBBjo7YiB" } } Here is the format of my request query. Could you please help me to resolve the issue.
