Unable to load replay with CherryVis

[Bruce Mackenzie Nielsen]

I have managed to build and run CherryVis, both on my local machine and in a Docker container, but in both cases I am not able to load a replay. When I click on the replay file, it writes "fetching : OK" in the status bar, but nothing else happens.

To aid in reproducibility, I've uploaded a repo with my Docker setup here: https://github.com/bmnielsen/cherryvis-docker

So the full reproduction steps are:

1. git clone https://github.com/bmnielsen/cherryvis-docker
2. cd cherryvis-docker
3. docker build -t cvis .
4. docker run -p 8770:8770 -it cvis
5. Open localhost:8770 in a browser (I'm using Chrome on Windows 10)
6. Select the MPQ files
7. Click on one of the sample replays

The browser console logs this error when loading initially:

GET http://localhost:8770/static/replays/viewer/test.js net::ERR_ABORTED 404 (Not Found)

Nothing is logged to the browser console when clicking the replay file.

Hi @bmnielsen, and thank you for reporting this issue.

test.js is the wasm file resulting of the build of OpenBW with emscripten - in your docker the build step fails (./build_js.sh). Your problem looks like a bug in asm2wasm to me (for instance WebAssembly/binaryen#1838).

As a workaround I would suggest that you use an older version: I personnaly use the version 1.38.13 for instance, so you would have to replace the first line of your dockerfile with:

FROM trzeci/emscripten:sdk-tag-1.38.13-64bit as builder

That did it, I didn't notice the build error from that step earlier. Thanks for the quick reply!
