So the problem here is that the JavaScript utilities of the BlazorExtensions.Storage library are not available in the JavaScript execution context.

Have you added the references listed under the 3rd item of the 'How to use' section of the readme to your index.html, specifically the blazor.extensions.storage.js reference?

<script src="_content/Caerostris.Services.Spotify/blazor.extensions.storage.js"></script>

If so, is the resource available at https://localhost:<port>/_content/Caerostris.Services.Spotify/blazor.extensions.storage.js? Does the network request succeed when your app is loading?

If all of the above questions can be answered with a clear 'yes', then I'll need access to the source code of your solution so that I can reproduce the issue locally.

Thank you for reporting the issue.
