Error URL

We are using Webkit to launch our UI and it has attachments(image/pdf). On download of attachments we get blob URL(blob:https://a.com/906fc2ec-6098-4942-b44b-bfcc94d298af) and on click it should open file. This is working fine in versions iOS 17.0 and below it. In version 17.1, 17.2 - we are getting this error - WebkitBlobResource error 1.

There are no changes in our code and same flow is working fine on Android/Web. 
This has impacted attachment functionality on all latest iOS devices. Requesting any updates/fixes went with latest release which could break support of rendering blob URL in Webkit?
