Blazor 8 Uncaught SyntaxError: Unexpected token '<'

Greg Finzer 0

I am stuck trying to convert from Blazor 7 Server to Blazor 8 Server. I am just about ready to give up, I don't think it is possible to use Blazor 8 with this defect in Blazor. I am using Blazor 8 Server. It is rendering CSS and JavaScript static files as garbage.

Here is my code for the App.razor

Hi @Greg Finzer, could you pls share what is your AddRemoveClass.js and SetGetValue.js?Make sure all your static files are accessible under the wwwroot directory and the paths are correct. If the issue persists, consider creating a minimal reproducible example to isolate the problem further.

you appear to have mapped js and ccs file to blazor routing, so you are getting the index page with a route request. probably bad configuration in program.cs. no guess what you have messed up.

you should create a .net 8 blazor app to see what the expected configuration is.

This is a defect in Blazor 8. Blazor 8 cannot handle a root path variable. Example:

@page "/{mylocation}/{mypageName}"

If you change it to this, it works:

@page "pages/{mylocation}/{mypageName}"I have submitted an issue to Microsoft:

https://github.com/dotnet/aspnetcore/issues/57192

I have also created a sample project with the steps to reproduce here:

its a bug in your code. your .js and .css files are relative paths. as you specified base "href" they should be absolute (start with "/"). when you add the root path, this changes the url, such that the static file handler does not process the request, but rather its a request that creates a new blazor app to processes the request, which returns the bootstrap html.

if you look at the urls in the browsers network trace you will see the error.

This is the workaround provided by Microsoft after they introduced this bug in Blazor 8.

This worked in Blazor 7 but not in Blazor 8:

@page "/{mylocation}/{mypageName}"

You have to put this in Blazor 8:

@page "/{mylocation}/{mypageName:nonfile}"
