[bug] tauri-apps/updater check

[AnthonyTB]

Describe the bug

When putting a raw json endpoint in the updater.endpoints section of tauri.conf I get (error sending request for url ("endpoint url")). If I click on the link via the console output it opens just fine in another window. I then tried to switch to the github releases file download option and it gets the same error (error sending request for url ("its a weird objects.githubusercontent aws link that 401's"))

Reproduction

tauri conf

"plugins": {
"updater": {
"active": true,
"pubkey": "dW50cnVzdGVkIGNvbW1lbnQ6IG1pbmlzaWduIHB1YmxpYyBrZXk6IEQ1NDVEQ0NDNkE1Q0U0MQpSV1JCenFYR3pGMVVEYmJoZ1lvcFd1dDlxVk9TSHlZTGZva0plbnAvMjd4ODZQdDM3eHVmZEloOQo=",
"endpoints": [
"https://github.com/AnthonyTB/port-24/releases/latest/download/latest.json"
]
}
}

package.json

"@tauri-apps/plugin-process": "2.2.0",
"@tauri-apps/plugin-updater": "2.6.1",

js implementation

check({ timeout: 30000 })
.then(async (data) => {
console.log("j", { data });
if (data) {
data
.downloadAndInstall()
.then(async (res) => {
console.log("h", { res });
await relaunch();
})
.catch((i_err) => {
console.log({ i_err });
});
} else {
console.log("no update");
setLoading(false);
}
})
.catch((err) => {
console.log({ err });
});

Expected behavior

Better error handling instead of just error requesting url and for it parse the json properly

When putting a raw json endpoint in the updater.endpoints section of tauri.conf I get (error sending request for url ("endpoint url")). If I click on the link via the console output it opens just fine in another window.

was that private maybe?

I then tried to switch to the github releases file download option and it gets the same error (error sending request for url ("its a weird objects.githubusercontent aws link that 401's"))

I don't see anything wrong with your setup - do you maybe have a proxy setup that doesn't work outside the browser (or at least not in the tauri app) or something like that?

Or maybe it was a server error? cause that link itself is somewhat correct but maybe github's cdn had problems. wouldn't be the first time.

I tried both secret/public gist

No I don't have any proxies setup

Or maybe it was a server error? cause that link itself is somewhat correct but maybe github's cdn had problems. wouldn't be the first time.

here's the url in the error that its saying it cant fetch. It works when inserting into a browser and even on a machine that has no github creds. But the updater cant fetch it or its giving a bad error and it is fetching it but something else is breaking.
