Our nightly export job crashed. I've attached the full log (export_2026-09-18.log). Read it and tell me the root cause and the exact line in our code where it fails.

Please **upload or paste the content of the `export_2026-09-18.log` file.**

As an AI, I cannot "see" files that haven't been provided in the chat interface. Once you paste the log content here, I will:

1.  **Analyze the stack trace** to identify the specific exception or error type.
2.  **Pinpoint the exact file and line number** referenced in the traceback.
3.  **Explain the root cause** (e.g., database timeout, null pointer, memory exhaustion, etc.).
4.  **Suggest a fix** for the issue.

**Pro-tip:** If the log is extremely long, please prioritize pasting the **last 50-100 lines**, or specifically the section containing the `Exception`, `Traceback`, or `Fatal Error`.
