Error hard to debug because of minified JS #54555

Open bruno-garcia opened 8 months ago

bruno-garcia commented 8 months ago

Is there an existing issue for this?

Describe the bug

The error is caused due to the client browser not supporting WebAssembly, or the version they support not having all features. So not a Blazor bug.

I'd like to dig deeper into such errors, but all the JS shipped by Blazor is minified (which makes sense).

Is the sourcemap generated as a result of that minification available anywhere?

Expected Behavior

Be able to do one of:

  1. Download Blazor's sourcemaps for each release
  2. Run webpack or whatever bundler so I can generate sourcemaps

This way I can either ship sourcemaps with my website or upload them to https://sentry.io

Steps To Reproduce

Shared (public) error: https://demo.sentry.io/share/issue/d24373d8406e48e2a3a3aa8725faf297/

Exceptions (if any)

No response

.NET Version

8.0.201

Anything else?

@thaystg do you know if there is a tooling support for this already?

@lewing Can you help with this one? I think it's more related to your side then debugger side.

@bruno-garcia We generate and provide source maps for .NET runtime JS files. It's enabled by default for build and you can explicitly enable it for publish with MSBuild property <WasmEmitSourceMap>true</WasmEmitSourceMap>.
