Question details
The user needs to retrieve an error code as proof for university staff after an online assignment submission failed, but the browser tab was closed before the code was recorded.

- Product
- Browser / Learning Management System
- Device & OS
- not provided
- Scenario
- Submitting an assignment online to a university portal or learning management system.
- Observed behavior
- An error occurred during submission, but the browser was closed before the exact error message or code could be documented.
Ensure your internet connection is stable and have a screenshot tool or keyboard shortcut ready before you attempt to submit your document again.
Reproduce the Submission Error
The most reliable method to get the exact error code is to replicate the conditions of the original failure and capture the code immediately.
Since browser tabs do not usually cache dynamic error messages from secure submission portals, the best approach is to trigger the error again.
Open your web browser, navigate to your university's assignment page, and log in to your account.
Select the exact same assignment file you tried to upload previously and click the 'Submit' button.
Do not close the tab. As soon as the error message or code appears on the screen, take a full screenshot (using Win + Shift + S on Windows or Cmd + Shift + 3 on Mac) to capture the code and the timestamp as proof.

Check Browser History for Error URLs
Occasionally, submission systems redirect you to a specific error page where the error code is written directly into the URL.
Prevent Upload Errors with WPS Office
Many assignment submission errors occur due to unsupported file types or corrupted formatting. Use WPS Office to cleanly format and reliably export your assignments into universally accepted formats, ensuring smooth submissions every time.
- 1. Open your assignment: Launch WPS Office and open your assignment document.
- 2. Export to PDF: Click on 'Menu' and select 'Export to PDF' to create a flattened, universally accepted file.
- 3. Submit the new file: Upload the newly generated PDF to your university portal to avoid formatting-related submission errors.

Frequently Asked Questions
Can the university IT staff see my failed submission even without the error code?
Yes, LMS administrators can typically check server logs for your user account to see failed upload attempts. However, providing the exact error code drastically reduces the time it takes them to locate the specific issue.
What are the most common causes of assignment submission errors?
The most common causes include exceeding the maximum file size limit, uploading unsupported file formats (such as .pages instead of .docx or .pdf), session timeouts from being idle too long, or brief server outages on the university's end.
How do I ensure my submission file isn't rejected?
Always check your university's submission guidelines before uploading. Typically, saving your document as a standard PDF or a DOCX file is the safest route. Also, ensure your file name does not contain special characters.
