Bug Report: ReferenceError: URLSearchParams Breaks Ad Loading on Consoles and Smart TVs

One-Line Summary: A ReferenceError for URLSearchParams occurs inside the IMA SDK's bridge iframe, causing widespread ad failures on key living room platforms including Xbox, PlayStation, Tizen, and WebOS.

---

Description

When an ad is requested using the latest version of the IMA SDK, the SDK's bridge iframe (bridge{version}_pl.html) executes code that calls URLSearchParams. This API is not natively supported on many modern console and smart TV web environments. As a result, a fatal ReferenceError: Can't find variable: URLSearchParams is thrown.

This suggests that the isolated iframe environment for the ad creative does not include the necessary polyfill for URLSearchParams, breaking the ad rendering process for a significant portion of CTV (Connected TV) traffic.

---

Environment

• SDK: Google IMA SDK for HTML5

• Version: Latest (as of September 2025)

• Platforms Affected: This is not limited to older desktop browsers. We have confirmed this error occurs on:

  • Xbox (all models)

  • PlayStation (PS4, PS5)

  • Tizen 3.0

  • WebOS 3.0

  • Other similar WebView-based environments.

---

Steps to Reproduce

1. Integrate the latest version of the Google IMA SDK on a webpage.

2. Load the page and request a VAST ad on any of the listed console or smart TV platforms.

3. Observe the developer console (via remote debugging).

---

Expected Result

The ad should load and play correctly. The IMA SDK's internal iframe should be self-contained and provide any necessary polyfills to ensure compatibility across all its supported devices, including major consoles and smart TVs.

---

Actual Result

A ReferenceError is thrown from within the SDK's bridge iframe, preventing the ad from loading. This critical bug blocks monetization on key living room devices.

Suggested Fix: Please include a polyfill for URLSearchParams within the bridge iframe's context to ensure backward compatibility and restore functionality on affected platforms.
