Steps To Reproduce

We have not been able to repro. Crash is from ABKInAppMessageWindowController line 88 viewDidLoad > ABKInAppMessageHTMLBaseViewController.m - Line 116 viewDidLoad > Crash: Fatal Exception: NSInvalidArgumentException localhost/index.html is not a file URL

Expected Behavior

BrazeUICompat kit supports in-app messages and handles any errors gracefully without crashing

Actual Incorrect Behavior

We had one IAM running and it appeared to be crashing every time. We turned it off using an app version isNot filter, and crashes stopped.

We had just completed the minimal migration documented here: https://braze-inc.github.io/braze-swift-sdk/documentation/braze/appboy-migration-guide/

Hey @kkaliher, thanks for the detailed information! Based on the presence of localhost in the URL, it looks like there may be an issue with the baseURL property in the HTML in-app messages or perhaps a failure in deserializing the IAM at some point. We'll take a deeper look and keep you posted on any updates.

Hey @kkaliher, we have just released the SDK 6.2.0 which addresses this crash. Thanks for your patience.
