`Asset 'index.html' not found` error.

Hi. I put my Tauri in my main app. I should say my tauri app is a GUI for my main app and it goes in a deployment folder inside my main app. there is a cargo.toml file in my project root that has member item and my deployment folder path is maintained there. as usual, it must be started when run cargo builds on project root and it did, but I got Asset 'index.html' not found; fallback to index.html error. what the wrong?

while I can run it without any error when I execute yarn Tauri dev in the deployment folder itself.

In fact, I can run app with yarn tauri dev but, cannot run it with cargo run

Copy from my discord message: you need to disable/remove the default feature for the custom protocol. Either by removing the default = ... line in cargo.toml or via cargo run --no-default-features or whatever else you can think of.

Hello @FabianLars,
Thank you for your answer.
I get the same issue, as I am i'm trying to run a sidecar node app, that works as standalone.
Removing the default line doesn't fix the issue, but removing the custom-protocol = [ "tauri/custom-protocol" ] line does make cargo run succesful. But I cannot build that way as i get an error.
Any ideas?
Many thanks!

@Jampard If you don't manually run it in a terminal, make sure you don't run it as cargo run --all-features (for example vscode/rust-analyzer has an option for this).
Otherwise check your configuration (devPath, distDir, window url).
If this doesn't help then i probably need more info or better yet a minimal reproduction.

Is it possible to disable the fallback?
I create a loader, that loads an URL, if not found, it loads another URL (theming, if file not found in theme dir, it uses default).
The fallback to .html make this not possible. Browser did not use a fallback.

Is it possible to disable the fallback?

Nope, but feel free to open a feature request for this.

Same issue, but with a different cause.

In my case, the distDir in tauri.conf.json was wrong. Corrected by changing distDir to where index.html actually locates.

For other's reference.
