From 12df88d196a095cba020dbdf82361def2acb3d8a Mon Sep 17 00:00:00 2001 From: oib Date: Sat, 28 Feb 2026 21:58:53 +0100 Subject: [PATCH] fix(blockchain-explorer): fix template formatting and enhance health check endpoint - Fix CSS animation syntax in HTML template by escaping curly braces for proper f-string formatting - Replace .format() with .replace() for node_url substitution to avoid KeyError with unescaped braces - Add blockchain node connectivity test to health check with 5s timeout - Return degraded status when node is unreachable instead of error - Add node_status field and API endpoints documentation to health response --- EXPLORER_FINAL_STATUS.md | 176 +++++++++++++++++++++++++++++++ apps/blockchain-explorer/main.py | 24 +++-- test_explorer_live.py | 78 ++++++++++++++ verify_explorer.py | 125 ++++++++++++++++++++++ 4 files changed, 397 insertions(+), 6 deletions(-) create mode 100644 EXPLORER_FINAL_STATUS.md create mode 100644 test_explorer_live.py create mode 100644 verify_explorer.py diff --git a/EXPLORER_FINAL_STATUS.md b/EXPLORER_FINAL_STATUS.md new file mode 100644 index 00000000..e03ed344 --- /dev/null +++ b/EXPLORER_FINAL_STATUS.md @@ -0,0 +1,176 @@ +# Explorer Issues - Final Status Report + +## 🎯 **ISSUES ANALYSIS & STATUS** + +Based on your re-check, I investigated the current state of the Explorer functionality.
