Regenerate Search Index not working in custom app created through frappe_docker

[adarshkh2397]

Information about bug

When clicking on Regenerate Search Index (under general settings section of helpdesk) leads to an API error with 500 code.
I have attached a screen recording for reference. The helpdesk app has been installed according to the steps mentioned in
custom app.md in frappe_docker.
