Multiple calls from js.InvokeAsync<IJSObjectReference>

[tossnet]

Hello, I don't understand why I can't make multiple calls to js.InvokeAsync.
from one of 2 JS files like this :

JSClippy ??= await js.InvokeAsync<IJSObjectReference>("import", "./Components/Agents/Clippy.razor.js"); JSDragDrop ??= await js.InvokeAsync<IJSObjectReference>("import", "./Components/Agents/draganddrop.js");

At this point, I have this error :

However, if I move my ‘draganddrop.js’ file to wwwroot it works :

JSClippy ??= await js.InvokeAsync<IJSObjectReference>("import", "./Components/Agents/Clippy.razor.js"); JSDragDrop ??= await js.InvokeAsync<IJSObjectReference>("import", "./draganddrop.js");

Do you know the answer?
