Uh oh - hmm - are you starting the server using start.sh ?

thread 'main' panicked at 'File not found: Os { code: 2, kind: NotFound, message: "No such file or directory" }'

Seems like the bundle.js isn't being found here https://github.com/chinedufn/percy/blob/44d974d325a52b66e022c343eb6226b2644cb607/examples/isomorphic/server/src/server.rs#L81-L84 ..

Does ./examples/isomorphic/client/bundle.js exist in your file system?

@hmobrienv Does this problem only occur in chrome? (try to open http://127.0.0.1:7878 in firefox)

if so, add favicon.ico at ./examples/isomorphic/client/favicon.ico and start it.

FILENAME: ./examples/isomorphic/client/favicon.ico

@eswr Occurs in both firefox and chrome.

@chinedufn There is no bundle.js file in ./examples/isomorphic/client/bundle.js.

[chinedufn]

Hmm, mind pasting the output from when you run start.sh ? I’m thinking there might’ve been a webpack build error or something.

[mikeyobrien]

Sure thing,

wasm-bindgen: command not found

It looks like you're missing one of the dependencies. Sorry! The instructions should have done a better job of explaining how to get yourself set up :(

I've updated the instructions to include the fact that you need to have nightly Rust and wasm-bindgen installed!

If those steps don't work for you let me know!
