Тест узла TypeScript не может быть изменен свойство? ⇐ Javascript

[Anonymous]

Итак, у меня есть этот тест в моем проекте TypeScript, и когда я выполняю мак -тест, два теста не провалили, что все проблемы связаны с TypeError [Error]: невозможно переопределить свойство: FetchAndnormalizePullRequests Я все время смотрел и не смог найти способ решить проблему. Это < /p>

И это моя функция fetchandnormalizepullRequest < /p>
import axios from 'axios';
import type{ NormalizedPR } from '../types/types.js';

export const fetchAndNormalizePullRequests = async (owner: string, repo: string, token: string): Promise => {
const url = `https://api.github.com/repos/${owner}/$ ... ?state=all`;

try {
const response = await axios.get(url, {
headers: {
Authorization: `token ${token}`,
'Content-Type': 'application/json',
},
});

return response.data.map((pr: any) => ({
prNumber: pr.number,
title: pr.title,
creator: pr.user.login,
creationTimestamp: pr.created_at,
requestedReviewers: pr.requested_reviewers.map((reviewer: any) => reviewer.login),
lastActionType: pr.merged_at ? 'merged' : pr.state,
lastActionTimestamp: pr.updated_at,
}));
} catch (error) {
throw new Error('Failed to fetch pull requests from GitHub API.');
}
};
