Invalid Account error using API request (error code = PIC-018)

I just got my app promoted to production and was testing api calls. For the below request I am getting back the error "Invalid Account". I am taking "owner_id" from the oauth oken results (Just like i did in the sandbox environment which worked) and supplying that as the accountID. Why does this work in the sandbox and not prodution

API Request:

https://platform.ringcentral.com/restapi/v1.0/account/<accountId goes here>/message-store-report

Result:

{

"errors": [

{

"errorCode": "PIC-018",

"message": "Invalid account"

}

]

}
