Catch error if no account selected in window pop up (Unhandled Promise Rejection: Error: Popup window closed)

[syedkhairi]

Hello!

Just wondering if possible to return error on picker:error if the retrieveAccessToken throw error. For example, if the user did not select any account when pop up window appeared, which caused [Error] Unhandled Promise Rejection: Error: Popup window closed (anonymous function) (@googleworkspace_drive-picker-element.js:91:172)

I assume adding catch and dispatch to picker:error to say no access token?

// OAuth token is required either as an attribute or from the OAuth flow using the client ID and scope
const oauthToken =
	this.getAttribute("oauth-token") ??
	(await retrieveAccessToken(
		// biome-ignore lint/style/noNonNullAssertion: just let the error bubble up when null
		this.getAttribute("client-id")!,
		this.getAttribute("scope") ??
			"https://www.googleapis.com/auth/drive.file",
	).then((token) => {
		this.dispatchEvent(
			new CustomEvent("picker:authenticated", { detail: { token } }),
		);
		return token;
	}));

At the moment, using this on Svelte, with a button state to toggle component, but if the popup window closed without account selection, no callback to reset the button state.

Need to implement the error_callback and response.error.
