+# telegram Markdown Code Block Format Fix Log 2025-12-15
+
+## Problem
+
+Error when sending message after chart generation:
+```
+❌ Chart generation failed: Can't parse entities: can't find end of the entity starting at byte offset 168
+```
+
+## Cause
+
+The Markdown code block format in the `header` message in `bot.py` is incorrect.
+
+The original code used string concatenation, adding `\n` after ```, which prevented the Telegram Markdown parser from correctly recognizing the code block boundary:
+
+```python
+# Incorrect usage
+header = (
+    "```\n"
+    f"{filename}\n"
+    "```\n"
+)
+```
+
+## Fix
+
+Changed to use triple-quoted strings, ensuring ``` is on its own line:
+
+```python
+# Correct usage
+header = f"""Report in attachment
+```
+{filename}
+{ai_filename}
+```
+"""
+```
