Stuck on an issue?

Hello,

I’m having the following issue after upgrading to Angular 9 and v5.4.0 of ngx-material-timepicker.

core.js:3866 ERROR TypeError: Cannot read property 'minutesGap' of undefined
    at TimepickerDirective.set [as value] (ngx-material-timepicker.js:1350)
    at Object.ngOnChangesSetInput [as setInput] (core.js:19023)

Timepicker is used as follow.

<input
  matInput
  placeholder="start time"
  aria-label="start time"
  [ngxTimepicker]="startTime"
  [format]="24"
  [value]="startTimeValue"
/>
<ngx-material-timepicker-toggle
  class="svg-color"
  [for]="startTime"
></ngx-material-timepicker-toggle>
<ngx-material-timepicker
  #startTime
  [defaultTime]="startTimeValue"
  [minutesGap]="5"
  (timeSet)="onChangeHourStartTime($event)"
></ngx-material-timepicker>

But [minutesGap] is defined on <ngx-material-timepicker>. Am I missing something ?
