JICS Transaction Runner Front End Blank

The issue you're experiencing with a blank screen in the JICS Transaction Runner is a known problem that can occur for various reasons. Here are some potential solutions and troubleshooting steps you can try:

1. Refresh the browser: Sometimes, simply refreshing the page can resolve the blank screen issue.

2. Clear browser cache and cookies: Try clearing your browser's cache and cookies, as outdated data can sometimes cause display problems.

3. Try a different browser: If the issue persists in one browser, attempt to access the JICS Transaction Runner using an alternative browser to rule out browser-specific problems.

4. Check for browser extensions: Certain browser extensions may interfere with the application. Try disabling extensions, particularly any related to wallets or security, to see if that resolves the issue.

5. Verify transaction database: Ensure that your transaction database is properly populated. The "Transaction Not Found" message can occur if the database is empty. Check that the SQL file for populating the JICS database (typically located at jics/sql/initJics.sql in your S3 bucket) has been correctly deployed.

6. Inspect server logs: If possible, review the server logs to identify any specific errors or issues that might be causing the blank screen.

7. Confirm recent updates: AWS Blu Insights and related services receive regular updates. Ensure you're using the most current version and that your environment is up-to-date.

If these steps don't resolve the issue, it may be necessary to contact AWS support for further assistance, as there could be underlying configuration or deployment problems specific to your environment.
