I’m experiencing a blank white screen issue when accessing business.facebook.com. Any help would be appreciated!

URL: https://graph.facebook.com/debug_token?input_token={id_token}&access_token={appid|appsecret} Method: GET Params: {id_token} -> get from iOS client facebook sdk auth return {appid|appsecret} -> get from facebook app console Response: { "data":{ "is_valid":false, "scopes":[], "error":{ "code":190, "message":"Invalid OAuth access token - Cannot parse access token" } } }
Detail: At some point, we get the respose that show above from request url, and at same time, some request is working. Does anyone know what the reason is?

I'm using a card node and sending the payload using a WhatsApp API. However, as I did not add a white line to the body of the card node at the beginning of my request, it is still adding a white line. This issue is only with Android devices, not other devices.
