[locatorjs]: loading: Unsupported React renderer, only bundle type 1 (development) is supported but 0 (production) is found

Summary

• captureConsoleIntegration forwards every console.warn on the page to Sentry, including this unfiltered third-party LocatorJS extension warning.
• Event has no exception/stacktrace; it is a console breadcrumb, category 'console', logger 'console'.
• Message text is the literal LocatorJS runtime warning about unsupported production React bundle.
• sentry.ts registers captureConsoleIntegration with levels warn and error, forwarding all console output.
• IGNORED_CONSOLE_MESSAGES only lists Dash0 and Vue Devtools patterns, not LocatorJS.
• File history shows repeated follow-up fixes (fix: silence Dash0 telemetry export noise in Sentry #5784, fix: filter Dash0 SDK fetch failures from Sentry #5838, fix: Another version of Vue Devtools seems to be installed. Please enable only one version at a time. #6147) adding new ignore patterns as noise appeared.

Root Cause

• File: web_src/src/sentry.ts → isIgnoredConsoleMessage / Sentry.init beforeBreadcrumb()
• Pull Request: chore: Configure which events are captured by sentry #1194

Suggested Fix

Add a regex for the LocatorJS 'Unsupported React renderer' message to IGNORED_CONSOLE_MESSAGES so this known benign third-party warning is dropped like the Dash0/Vue Devtools cases.

web_src/src/sentry.ts:11-17
 export const IGNORED_CONSOLE_MESSAGES = [
   // Dash0 Web SDK logs export failures to the console.
   /^(Failed to send telemetry to|Error sending telemetry to|Failed to fetch)/,
   // Vue Devtools browser extension warns when multiple versions are installed.
   // Our app is React-only; this noise originates from the user's extensions.
   /^Another version of Vue Devtools/,
+  // LocatorJS browser extension/tool logs this when it inspects a production
+  // React build; unrelated to our app code.
+  /^\[locatorjs\]: loading: Unsupported React renderer/,
 ];
