Duplicate markers on the map. about vue2-gmap-custom-marker

[eregnier]

I have not enough clues with your code sample.
I guess your issue comes from markers data. You may check this content and find out why is there some duplicate markers.
I also may help more if you share me some shareable markers data. (you may share the whole annonymised for exemple.

I have no other issues like this until now and there are now quite some user using this plugin. I doubt this issue comes from this plugin, however if we find where does it comes from and in case this issue is related this plugin code, I'd be happy to fix it.

Let me know if you still need help on this topic.

Markers come from backend and has unique id. Marker example:
{"id":6,"lat":55.6668532,"lng":37.2757566}

I added check for marker existence (check by isAdded props in inst object) in afterCreate function and this fix my trouble with duplicates, but i received next error:
DOMException: Failed to execute 'insertBefore' on 'Node': The node before which the new node is to be inserted is not a child of this node.

This error appears only when an array with markers comes from the backend, and some of the past markers are missing from it.

Marker code:

<gmap-custom-marker
     v-for="marker in markers"
     v-bind:key="marker.id"
     :marker="marker.pos"
     @click.native="event => showFacility(marker.id, event)"
     @mouseover.native="receiveFacility(marker.id)"
     :z-index="marker.id === selectedMarkerId ? 50 : 10"
>
     <div class="map-marker">
          <div class="icon">
               <img src="/img/building.png" />
          </div>
          <div class="body" v-if="marker.id === selectedMarkerId">
              ...
          </div>
     </div>
</gmap-custom-marker>

try to wrap your custom markers into a div if you have many sibbling custom marker. This prevent vue to loose track of your components.

Let me know if this solved your issue.
