DevTools not serving properly on app refresh #56091

Open kenzieschmoll opened 3 months ago

Example URL: http://127.0.0.1:9102/cpu-profiler

The browser loads a blank white page with the message: "could not read file as String: cpu-profiler" (link)

Repro steps:

run DevTools with devtools_tool serve and open it. Refresh the page and observe this error.

This should be treated as a release blocker. The fix is likely on the server side in DDS and not in DevTools app, so @elliette you should still be able to move forward with the devtools app release into the Dart SDK.

Summary: DevTools fails to load profiler data after page refresh, displaying a "could not read file as String" error. The issue likely stems from a server-side problem in DDS, not the DevTools app.
