Debug Console points to files with \ instead of /

The report names no source files, tests, or entry points. First reproduce the VS Code Firefox debug configuration using the Windows client, SSH tunnel, and Ubuntu paths shown; done means remote file locations are displayed with forward slashes in the debug console.

I have a problem that inside Vscode debug console i see errors that points to the correct file, but with wrong slash \ instead of /.

Local: Windows 11, Cursor, Firefox latest
SSH tunnel to: Ubuntu server

It points to:
\srv\http\dev-test-prisma\frontend\src\modules\vehicle_forms\CrmEquipmentForm\CrmEquipmentForm.vue

Correct:
/srv/http/dev-test-prisma/frontend/src/modules/vehicle/_forms/CrmEquipmentForm/CrmEquipmentForm.vue

					"path": "/srv/http/dev-test-prisma/frontend/src/"
				}
			]
		}
	]
}

Anyone know how to change this?
