Getting attachments from payments

[adriaandotcom]

I'm trying to use the API and did setup Postman to find out why my code isn't working. Unfortunately in Postman I get the same error.

When I do a request to this endpoint {{host}}/v1/user/{{user_id}}/monetary-account/{{monetary_account_id}}/payment/{{payment_id}}/note-attachment with a recent payment (in the Bunq app the payment has an attachment) I get an error:

The provided object does note support notes.

When I get the payment there is no issue. But somehow the attachments are not working correctly. Is there anything I can do to get the attachments from the API?

It only seems to work for payments that happen between my own Bunq monetary accounts.
