Could not find 'CookieConsent.BroadcastEvent'

[CSHGK]

We have upgraded from 1.0.18 to 1.2.0 and now we get the following error on each load/reload:

invoke-js.ts:176 fail: BytexDigital.Blazor.Components.CookieConsent.CookieConsentService[0] Exception raised trying to run CookiePreferencesChanged event handler Microsoft.JSInterop.JSException: Could not find 'CookieConsent.BroadcastEvent' ('BroadcastEvent' was undefined).

Do you have an idea Thanks

Hi, it appears to work in a new project as far as I can see. Are you able to reproduce this issue in a minimal project? I'll check again in a minute what this could be, but at first glance im unable to tell

Hi, the error does not occur in a brand new minimal project. But the error occurs in our project also when we only set:

In App.razor: <BytexDigital.Blazor.Components.CookieConsent.CookieConsentHandler @rendermode="@RenderMode.InteractiveWebAssembly" />

In Programm.cs: builder.Services.AddCookieConsent(o => { });

In index.html: < link rel="stylesheet" href="_content/BytexDigital.Blazor.Components.CookieConsent/styles.min.css" />

What kind of project structure do you use? Is it a Blazor WebApp with interactive rendering or a 100% server-side or 100% WASM app?

[RyanTT]

I just tried creating a new WebApp project in Visual Studio with global interactivity enabled, and interactivity render mode on auto, then

• added <BytexDigital.Blazor.Components.CookieConsent.CookieConsentHandler @rendermode="@RenderMode.InteractiveWebAssembly" /> to my App.razor
• added builder.Services.AddCookieConsent(o => { }); in both the server Program.cs and the client's Program.cs
• added the required CSS to the App.razor

which worked fine. Could you send me your minimal project where the library did not work? That would greatly help me debug the issue.

Feel free to comment again and I'll reopen
