So i tried to hit the [https://api.servicem8.com/api\_1.0/Attachment/{attachment\_id}.file](https://api.servicem8.com/api_1.0/Attachment/%7Battachment_id%7D.file) with webclient in my code. But the response i’m getting is null while this works perfetcly fine in postman. I want to know what headers should i use to get the correct byte stream of the attachment file
