backport version-13-hotfix

🟠 Waiting for conditions to match

• merged [:pushpin: backport requirement]

[rtdany10]

Linters failing with error: The PR contains a SQL query that may be re-written with frappe.qb
Since we need to backport, I believe that can be ignored for the time being and be fixed in a future pull request.

[rtdany10]

Unrelated test failure?

[rtdany10]

@deepeshgarg007 tests all passing. Can we merge this PR?
