unsupported get request on fetching username and ID fields on instagram graph api call

hey, i recently implemented the instagram basic profile api, it works perfectly on my test account, i submitted my app for review and it was approved for the instagram basic profile api. I went live and i tried it on a different user, it returned an error code 100, unsupported get request with fbtrace and a certain number. Please how can i bypass this error, is there anything im doing wrong?
