net::ERR_CONTENT_LENGTH_MISMATCH returning large content when port-forwarding from devcontainer #9969

Open rokos-angus opened 5 months ago

rokos-angus commented 5 months ago

Type: Bug

VSCode 1.91.0-insider (reproducible with latest stable release) Docker version 25.0.3, build 4debf41 (installed within WSL, not docker desktop)

Run local devcontainer within WSL (ubuntu 22.04 image) Run any http webserver and port forward with vscode to windows host (I have best luck reproducing with flask python server) Access content from windows host browser. This seems to depend on the size of the content, most reliable when it is at least >100kb

Expected Behavior Content is successfully displayed in the browser

Actual Behavior Content appears to be truncated, browser logs Failed to load resource: net::ERR_CONTENT_LENGTH_MISMATCH

It is worth noting that this issue does NOT happen when running and port forwarding the application in WSL directly, ONLY when running in a devcontainer

Can you compare what the browser gets with the original? The WSL and Dev Containers extensions use the same port forwarding implementation, not sure what could cause this.

rokos-angus commented 5 months ago

Not quite sure what you mean by "the original" I have created a reproduction repo at https://github.com/rokos-angus/devcontainer-content-mismatch

Using this project I consistently see the content mismatch error in the devcontainer here but not windows or wsl. Interested if you see similar

WSL: image

Seeing it with Docker in WSL. I didn't see it on Mac. Using PowerShell to download from Docker in WSL shows that it sometimes works and sometimes doesn't get all bytes. Maybe we're closing some stream too early? /cc @alexr00

This issue has been closed automatically because it needs more information and has not had recent activity. See also our issue reporting guidelines.

Happy Coding!

rokos-angus commented 5 months ago

@chrmarti @alexr00 what more info did you need? Seems it was reproducible

JamesStratford commented 2 weeks ago

I'm dealing with this issue also. Dev container on WSL over remote-ssh.

Running Plotly Dash with Flask backend

About 50% of the time on page load I get net::ERR_CONTENT_LENGTH_MISMATCH
