Uncaught (in promise) Error: Error

Uncaught (in promise) Error错误通常是因为在使用Promise时未正确处理错误。根据提供的代码片段,有两种解决方法可以尝试:
1. 在使用axios请求接口时,在then()后加上catch(),以处理可能产生的错误。示例代码如下:
```javascript
export function stopMCUMixTranscode(params) {
return new Promise((resolve, reject) => {
axios
.post(`********`, params)
.then((res) => {
resolve(res);
})
.catch((err) => {
reject(err);
});
});
}
```
2. 使用返回`Promise.reject(new Error(res.msg || 'Error'))`来捕获和处理异常。在请求返回时,可以使用`.catch(err => { console.log(err) })`来捕获异常。示例代码如下:
```javascript
return Promise.reject(error)
.catch(err => {
console.log(err);
});
```
希望以上解决方法能够帮助你解决Uncaught (in promise) Error错误。

Error: Uncaught (in promise): Error: NG04002
回答: 根据引用\[1\]和引用\[2\]的内容,你遇到的错误是因为在拦截器中的判断逻辑不正确导致的。在拦截器中,别人的判断是当response.data.status不等于1时,即认为请求失败,然后通过Promise.reject(rejection)来抛出错误。而你修改后的判断是当response.data.status等于200时,即认为请求成功,但实际上这个判断是错误的。所以你需要将判断逻辑修改为response.data.status !== 1,这样才能正确处理请求失败的情况。根据引用\[3\]的内容,"Error: Uncaught (in promise): Error: NG04002"是一个未被发现的错误,你之前可能认为是前端代码的问题,但经过排查后发现前端代码没有问题。因此,你需要仔细检查拦截器中的判断逻辑,确保正确处理请求的返回状态。

Uncaught (in promise) Error:
Uncaught (in promise) Error: This error occurs when a promise is rejected but there is no catch() or error handling mechanism to handle the rejection. It means that an asynchronous operation failed and was not properly handled.
To resolve this error, you should add a catch() block to the promise chain to handle any errors that may occur. This allows you to gracefully handle the rejected promise and prevent the error from being uncaught.
Here's an example of how you can handle the error using catch() method:
```javascript
myPromise
.then(result => {
// Code to handle the successful result
})
.catch(error => {
// Code to handle the error
console.error('An error occurred:', error);
});
```
By adding the catch() block, you can handle any errors that occur during the promise execution and prevent the "Uncaught (in promise) Error" from being thrown.
