I am encountering a persistent error in App Store Connect when attempting to save URLs in the App Clip URLs section of my app version.
The issue is as follows: When I enter the URL (e.g., https://4o.c.smart321.com/c/l0) and click save, I receive a 409 Conflict error with the code ENTITY_ERROR.ATTRIBUTE.TYPE. The error detail states: "does not match the uri pattern must be a valid RFC 3986 URI".
The Error Log: { "errors" : [ { "id" : "9f032dd6-f456-4c90-ad9c-245c5ed041d7", "status" : "409", "code" : "ENTITY_ERROR.ATTRIBUTE.TYPE", "title" : "An attribute in the provided entity has the wrong type", "detail" : "does not match the uri pattern must be a valid RFC 3986 URI", "source" : { "pointer" : "/data/attributes/invocationUrls/1" } } ] } Conflicting Status: Interestingly, the exact same URL has already been configured under Advanced App Clip Experiences, where it currently shows a status of "Received".
My AASA file is https://4o.c.smart321.com/.well-known/apple-app-site-association
I have verified that the URL follows the standard HTTPS format and contains no hidden characters. Could you please clarify why the URL is being rejected in the App Version section while being accepted in the Advanced Experiences section?
