How to solve this error? "InvalidValueError: not an instance" (google autocomplete)

Ionic Framework ionic-v3
1

I’m using the IONIC framework and I’m trying to implement the autocomplete fields in the Google Maps API. When it does not work on my project on which work I have tried to create a blank project to test the code. To my surprise there it works:

Code that works( index.html ):

    <div id="locationField">
      <input id="autocomplete" placeholder="Enter your address"
             onFocus="geolocate()" type="text"></input>
    </div>

    <script>

var placeSearch, autocomplete;
/*var componentForm = {
  street_number: 'short_name',
  route: 'long_name',
  locality: 'long_name',
  administrative_area_level_1: 'short_name',
  country: 'long_name',
  postal_code: 'short_name'
};*/

function initAutocomplete() {
  // Create the autocomplete object, restricting the search to geographical
  // location types.
  autocomplete = new google.maps.places.Autocomplete(
      /** @type {!HTMLInputElement} */(document.getElementById('autocomplete')),
      {types: ['geocode']});

  // When the user selects an address from the dropdown, populate the address
  // fields in the form.
  autocomplete.addListener('place_changed', fillInAddress);
}

// [START region_fillform]
function fillInAddress() {
  // Get the place details from the autocomplete object.
  var place = autocomplete.getPlace();

  for (var component in componentForm) {
    document.getElementById(component).value = '';
    document.getElementById(component).disabled = false;
  }

  // Get each component of the address from the place details
  // and fill the corresponding field on the form.
  for (var i = 0; i < place.address_components.length; i++) {
    var addressType = place.address_components[i].types[0];
    if (componentForm[addressType]) {
      var val = place.address_components[i][componentForm[addressType]];
      document.getElementById(addressType).value = val;
    }
  }
}
// [END region_fillform]

// [START region_geolocation]
// Bias the autocomplete object to the user's geographical location,
// as supplied by the browser's 'navigator.geolocation' object.
function geolocate() {
  if (navigator.geolocation) {
    navigator.geolocation.getCurrentPosition(function(position) {
      var geolocation = {
        lat: position.coords.latitude,
        lng: position.coords.longitude
      };
      var circle = new google.maps.Circle({
        center: geolocation,
        radius: position.coords.accuracy
      });
      autocomplete.setBounds(circle.getBounds());
    });
  }
}
// [END region_geolocation]

    </script>
    <script src="https://maps.googleapis.com/maps/api/js?key=AIzaSyAerQ5pzis73-ojGb2D-Rom3NFiS5s1Y7U&libraries=places&callback=initAutocomplete"
        async defer></script>
</html>

On the other hand, in the project in which I want to include this code (tabs project) I have it put this way:

compartir.html:

<div id="locationField">
  <input id="autocomplete" placeholder="Enter your address"
         onFocus="geolocate()" type="text"></input>
</div>

index.html:

  <script>

    var placeSearch, autocomplete;
    /*var componentForm = {
      street_number: 'short_name',
      route: 'long_name',
      locality: 'long_name',
      administrative_area_level_1: 'short_name',
      country: 'long_name',
      postal_code: 'short_name'
    };*/

    function initAutocomplete() {
      // Create the autocomplete object, restricting the search to geographical
      // location types.
      autocomplete = new google.maps.places.Autocomplete(
          /** @type {!HTMLInputElement} */(document.getElementById('autocomplete')),
          {types: ['geocode']});

      // When the user selects an address from the dropdown, populate the address
      // fields in the form.
      autocomplete.addListener('place_changed', fillInAddress);
    }

    // [START region_fillform]
    function fillInAddress() {
      // Get the place details from the autocomplete object.
      var place = autocomplete.getPlace();

      for (var component in componentForm) {
        document.getElementById(component).value = '';
        document.getElementById(component).disabled = false;
      }

      // Get each component of the address from the place details
      // and fill the corresponding field on the form.
      for (var i = 0; i < place.address_components.length; i++) {
        var addressType = place.address_components[i].types[0];
        if (componentForm[addressType]) {
          var val = place.address_components[i][componentForm[addressType]];
          document.getElementById(addressType).value = val;
        }
      }
    }
    // [END region_fillform]

    // [START region_geolocation]
    // Bias the autocomplete object to the user's geographical location,
    // as supplied by the browser's 'navigator.geolocation' object.
    function geolocate() {
      if (navigator.geolocation) {
        navigator.geolocation.getCurrentPosition(function(position) {
          var geolocation = {
            lat: position.coords.latitude,
            lng: position.coords.longitude
          };
          var circle = new google.maps.Circle({
            center: geolocation,
            radius: position.coords.accuracy
          });
          autocomplete.setBounds(circle.getBounds());
        });
      }
    }
    // [END region_geolocation]

        </script>
        <script src="https://maps.googleapis.com/maps/api/js?key=AIzaSyAerQ5pzis73-ojGb2D-Rom3NFiS5s1Y7U&libraries=places&callback=initAutocomplete"
            async defer></script>

When running it does not appear errors in console, but nevertheless when analyzing the network of the navigator I encounter this error:

InvalidValueError: not an instance of HTMLInputElement  ?    ionicplatform=ios:28
