When I try to send a message request, I receive the error: "App is not connected to the business" (code 100, subcode 2534039). Does anyone know what might be causing this? This error does not occur on all Instagram accounts. Here is the full error message:

{ "error": { "message": "Invalid parameter", "type": "OAuthException", "code": 100, "error_subcode": 2534039, "is_transient": false, "error_user_title": "App is not connected to the business", "error_user_msg": "The app is not connected to the business", "fbtrace_id": "..." } }
