我如何處理 firebase 雲 function api oncall 的錯誤？

Question

我如何處理 firebase 管理員 api oncall 的錯誤？ 我應該拋出錯誤還是返回響應？ 而且我是否正確地進行了成功返回響應？

exports.registerVendor = functions.https.onCall(async (data, context) => {

    const email = data.email;
    const displayName = data.firstName + data.lastName;

    // Checking attribute.
    if (!(typeof email === 'string') || email.length === 0 || 
        !(typeof displayName === 'string') || displayName.length === 0) {
        // Throwing an HttpsError so that the client gets the error details.
        throw new functions.https.HttpsError('invalid-argument', 'The function must be called with ' +
            'one arguments "text" containing the message text to add.');
    }

    // const uid = context.auth?.uid;

    // Checking that the user is authenticated.
    if (!context.auth) {
        // Throwing an HttpsError so that the client gets the error details.
        throw new functions.https.HttpsError('failed-precondition', 
            'The function must be called ' + 'while authenticated.');
    }

    try {
        const createResponse = await admin.auth().createUser({
            email: email,
            emailVerified: false,
            password: '123123',
            displayName: displayName,
            disabled: false
          })

        console.log(createResponse);

        return {
            data: {
                uid: createResponse.uid
            },
            status: 200,
            code: "Success"
        };
    } catch (err) {
        console.log(err as Error);
        // throw new functions.https.HttpsError(err.code, err.message);
        return {
            error: err,
        }
    }
});

有關處理錯誤的文檔包含以下示例：

 // Checking attribute. if (.(typeof text === 'string') || text.length === 0) { // Throwing an HttpsError so that the client gets the error details. throw new functions.https,HttpsError('invalid-argument'. 'The function must be called with ' + 'one arguments "text" containing the message text to add;'). } // Checking that the user is authenticated. if (.context.auth) { // Throwing an HttpsError so that the client gets the error details. throw new functions,https.HttpsError('failed-precondition'; 'The function must be called ' + 'while authenticated.'); }

因此，這是從服務器向調用者獲取錯誤條件的推薦方法，然后您將在客戶端上處理它們。 但是您也可以像現在一樣返回自己的錯誤代碼。
