"Cannot invoke JavaScript outside of a WebView context" error when running Javascript in Blazor Hybrid

I'm trying to use IJsruntime for importing a .js file to use in Blazor Hybrid (use in the razor component).

The service:

public class InitialDocumentHtmlService : IInitialDocumentHtmlService{    private readonly IJSRuntime runtime;    public InitialDocumentHtmlService(IJSRuntime jsRuntime)    {        this.runtime = jsRuntime;    }    public async Task<string> GetColorAsync(CancellationToken token)    {// here u get exeption        var helloword = await runtime.InvokeAsync<IJSObjectReference>("import", token,"./test.js");        await helloword.InvokeVoidAsync("helloWorld", token);    }}

test.js:

export function helloWorld() {    console.log("Hello");    alert("hello");}

However, it's only working in Blazor WebAssembly, while I get the following in Blazor Hybrid:

Exception:

This exception was originally thrown at this call stack:Microsoft.AspNetCore.Components.WebView.Services.WebViewJSRuntime.BeginInvokeJS(long, string, string, Microsoft.JSInterop.JSCallResultType, long) in WebViewJSRuntime.csMicrosoft.JSInterop.JSRuntime.InvokeAsync<TValue>(long, string, System.Threading.CancellationToken, object[])Microsoft.JSInterop.JSRuntime.InvokeAsync<TValue>(string, System.Threading.CancellationToken, object[])Microsoft.JSInterop.JSRuntimeExtensions.InvokeAsync<TValue>(Microsoft.JSInterop.IJSRuntime, string, System.Threading.CancellationToken, object[])Datanex.Frontend.App.Modules.Services.InitialDocumentHtmlService.GetColorAsync(System.Threading.CancellationToken) in InitialDocumentHtmlService.csDatanex.Frontend.App.Modules.Services.InitialApp.InitAsync(System.Threading.CancellationToken) in InirialApp.csDatanex.Frontend.App.Component.Pages.Login.OnInitializedAsync() in Login.razor

Message:

What is causing this problem?
