proof jwt is empty string

[cindy-chin]

Hi, I have recently try out the authorization code flow in the mobile app. I found that, if there are now issuer, the iss field in proof jwt will be empty string. from the specification, seems like only in pre-authorisation code flow can omit iss, even if iss is omitted, I not pretty sure if it should be empty string.

example { "iss": "", "aud": " [https://e9b4-119-73-236-216.ngrok-free.app/oid4vci/test/test-issuer"](https://e9b4-119-73-236-216.ngrok-free.app/oid4vci/test/test-issuer%22) , "iat": 1716947280, "nonce": "u76wqIVIFXwudmPYZwtE0N1xIRMKyVRX" }

Thank you, sorry for bothering so much
