5 years ago Hi @hannespreishuber,
I ran into a similar (the same) issue, when trying to read the location of the user using the LocationService. This is the error in the console:
I found a workaround by copying the Location.js in the wwwroot of my application https://github.com/AspNetMonsters/Blazor.Geolocation/blob/9a7ab1b06cfeee05a5130e89f7ac9404bddfc126/AspNetMonsters.Blazor.Geolocation/wwwroot/Location.js#L1
And then referencing it in my index.html or _Host.cshtml (if you're using Blazor Server Side).
However, I think when installing the NuGet package the file should be copied to your wwwroot.
Hope that helps :)
P.S. I am a Blazor novice and someone more experienced may give better advice. I am just sharing what fixed my issue
try to get it run with 3.0 final protected override async Task OnInitAsync() should be in readme.md protected override async Task OnInitializedAsync()
but at this point I get a NullReferenceException: Object reference not set to an instance of an object.

var result = await jSRuntime.InvokeAsync("AspNetMonsters.Blazor.Geolocation.GetLocation", requestId);
