Hi,

Welcome to the community!

Your version is past EOL. You should upgrade to either the latest version or the current LTS at your earliest convenience. Your upgrade path is:

7.7 → 7.9.6 → 8.9.9 → 9.6 (last step optional)

You may find the Upgrade Guide and the LTS-to-LTS Upgrade Notes helpful. If you have questions about upgrading, feel free to open a new thread for that here.

If your error persists after upgrade, please come back to us.
