I've been wrestling with this for quite a while now. I have a working blazor (auto - hybrid) project called CustomerPortal and it created a CustomerPortal.Client for me as well.
I created a 2 razor components, ServerTime and ClientTime which just shows the current time and keeps on updating it. This page works fine, up to the point where i introduce authorization in my program.cs. Suddenly i get a javasscript error and the blazor interactivity is gone (my time won't update anymore and buttons will no longer work). Both the client side timer as the server side timer will stop working on this same error.
Error is as follows:blazor addauthorization Uncaught SyntaxError: expected expression, got '<'` in the blazor.web.js file
The only thing i add to my program.cs file is this:`
builder.Services.AddAuthorization(options =>{ options.FallbackPolicy = options.DefaultPolicy;});This seems to put the blazor interactivity files behind authorization as well. I have tried numerous solutions but I keep getting the same error. if i remove these lines it works again. Does anyone know how to fix this?
My full Program.cs for transparency:`
