[Bug] Convex CLI fails on windows due to the `:` in path

[arduano]

This line gets hit when trying to run convex dev on windows:

convex-backend/crates/convex/sync_types/src/path.rs

Line 25 in 5536b75

"Path component {s} can only contain alphanumeric characters, underscores, or periods."

Here's a sample (simplified) error that I get when I run it:

✖ Error fetching POST  http://my.convex.instance:3210/api/prepare_schema 400 Bad Request: BadConvexModuleIdentifier: C:/path/to/repo/out/schema.js is not a valid path to a Convex module. Path component C: can only contain alphanumeric characters, underscores, or periods.

I'm not sure what the ideal solution would be, but I'm confused why a server-side error would be happening due to dev-side configuration. Maybe using relative paths relative to the closes .git folder would be better?

Agreed! Likely a bug somewhere. The idea is that a "Convex Module Identifier" should be something platform agnostic.

Clientside path (samples)
C:\nipunn\repo\convex\dir\file.ts
/Users/nipunn/repo/convex/dir/file.ts

Module path
dir/file.js

The CLI should be converting these properly before it gets to the server. There's probably a bug somewhere. Do you have a repro? Like a small repo that hits this issue?

Alternately, do you have the name of the cloud deployment that you're developing against? If so, then we can look at logs there. Should be in your .env.local.

I'm deploying against self-hosted because I'm just testing the feasibility of some things and learning more about Convex. Unfortunately I'm stuck with windows in my enterprise-scale company for more reasons than one haha

I'm using these images: ghcr.io/get-convex/convex-backend:6efab6f2b6c182b90255774d747328cfc7b80dd9 ghcr.io/get-convex/convex-dashboard:6efab6f2b6c182b90255774d747328cfc7b80dd9

My repro would just be: spin up a local node repo with convex on windows, run convex dev

[arduano]

I abbreviated to my.convex.instance:3210 in my error because it's just a local IP address

[nipunn1313]

self-hosting on windows is not as battle tested as on other platforms (since we run cloud convex on linux ourselves).

Windows should work, but I'm not surprised to find little bugs like this. We'd love to get self-hosted windows to a stronger state, but in the meantime you can probably try testing things out with cloud convex dev deployment.

We'll take a look when we get to it - or if someone in the community wants to try and repro and fix, we'd take a PR.

[arduano]

No like, I self-host on a linux server, and I use the dev cli from windows

a local IP address

An IP of another linux machine on my LAN

[nipunn1313]

oh - that should definitely work. Likely a bug in the CLI.

hi @nipunn1313 , i tried to make the path normalization changes , should i create a PR to review changes
