SSE Recovery Issue - Root Cause Found & Fixed

Output

🔧 SSE Recovery Bug Investigation CompleteRoot CauseThe pollForOutput() function was crashing with TypeError: can't access property "filter", todos is undefined because the fix from earlier wasn't deployed - konui needed to be restarted.
Evidence from LogsBefore restart (08:16-08:17):
Poll error: TypeError: can't access property "filter", todos is undefined
Poll error: TypeError: can't access property "filter", todos is undefined
(repeated 30 times...)After restart (08:24+):
[Client:poll] No output or progress yet {attempt: 1, progressFound: false}
[Client:poll] No output or progress yet {attempt: 2, progressFound: false}
(working correctly, no errors)
Fix Summary (3 issues)currentRequestId undefined - Fixed in lines 1895, 1964
Missing progress check in polling - Added checkForProgress() call
TypeError on undefined todos - Added Array.isArray(progress.todos) guard
What Was HappeningUser navigates away from Dashboard → SSE stream dies
User navigates back → page_visible triggers recovery
Recovery calls pollForOutput()
Polling calls checkForProgress() which returns {found: true, todos: undefined}
CRASH: progress.todos.filter() fails on undefined
Polling loop catches error, continues, but UI never updates
Next StepsThe fix is now deployed. You can test by:
Send a prompt on Dashboard
While Claude is working (todo updates visible), switch to Kontasks page
Wait a few seconds, switch back to Dashboard
Status bar should update and final kontask card should render
