Release Focus: Safari Compatibility Fix - Background Image Loading

What’s New

This is a hotfix release addressing a critical rendering issue on Safari (macOS) where the seatmap background would fail to load, causing the venue map to disappear.

Bug Fixes

Critical Fixes

  • Background image fails to load on Safari (414 Request URI Too Long): When the blurred background preview is delivered as inline base64 data, the renderer incorrectly treated it as a relative URL path. This caused the browser to construct an enormous HTTP request (appending the entire base64 payload to the page URL), which the server rejected with a 414 status code. The seatmap would then render without any background image.
    • Affected browsers: Safari on macOS (stricter URL length limits than Chrome/Firefox)
    • The renderer now correctly detects inline base64 PNG data and wraps it as a proper data URL
    • Improved error messages for image loading failures to include the target URL for easier debugging

What’s Inside

This release includes a targeted fix for background image loading:

Main Changes:

  1. Base64 detection in URL resolver - Raw base64 PNG data is now recognized and wrapped as a data:image/png;base64,... URL before loading
  2. Image load error reporting - Error handler now includes a truncated URL preview and handles browser-specific error object differences

Components Updated:

  • Booking Client (Renderer) - Background image URL resolution and error handling
