new window created by external URL like file:///D:/..... cannot communicate by IPC

[fuyifan]

WebviewWindowBuilder::new(
app,
"main",
WebviewUrl::External("file:///D:/test/index.html")
)
.title("test")
.center()
.build()?;

the new window cannot communicate with exe by IPC. Any recommend or solution?

Maybe try this? https://v2.tauri.app/security/capabilities/#remote-api-access file urls aren't explicitly supported so no guarantees.

I have added following setting in default.json
"remote": { "urls": [ "https://*", "http://*", "file:///*" ] }, "domains": ["*"]

it doesn't work

[FabianLars]

do you see any errors in the devtools console?

[fuyifan]

ipc.localhost/fetch_data:1 Failed to load resource: the server responded with a status of 500 (Internal Server Error)

huh, that's a weird one 🤔 would you mind opening a bug report issue for that one?

Here's the relevant feature request btw #5302 (not about file:// urls specifically but its solution should work for your use case as well i guess)
