Api tools no hot reaload and error console

Bug Report

Hello @all

In my local development under win 10, php 7.3, Laminas API Tools 1.5.1dev, Firefox developer edition,
I don’t have a refresh of the REST edition page.

I have this js error in the console:
Error: [ngRepeat: dupes] Duplicates in a repeater are not allowed. Use ‘track by’ expression to specify unique keys. Repeater: field in vm.rest.fields, Duplicate key: string: <, Duplicate value: “<”

d / <@http: // localhost: 8080 / api-tools-ui / 9e2f6fa1.vendor.js: 3: 22725

Anyone have the solution?
