All of the feathers errors can be provided with a custom message, which overrides the default message in the payload:

<pre><code>throw new GeneralError('The server is sleeping. Come back later.');
</code></pre>

You can also pass additional data and/or errors. It's all documented: <a href="https://docs.feathersjs.com/api/errors.html" rel="nofollow noreferrer">https://docs.feathersjs.com/api/errors.html</a>

As per @daff comment above, this is how you can customize the returned error object. Here includes extending built-in errors as well as a custom error
custom-errors.js
<pre><code>const { FeathersError } = require('@feathersjs/errors');

class CustomError extends FeathersError {
 constructor(message, name, code) {
 super(message, name, code);
 }

 toJSON() {
 return {
 status: &quot;Failed&quot;,
 code: this.code,
 detail: this.message,
 }
 }
}

class BadRequest extends CustomError {
 constructor(message) {
 super(message, 'bad-request', 400);
 }
}

class NotAuthenticated extends CustomError {
 constructor(message) {
 super(message, 'not-authenticated', 401);
 }
}

class MyCustomError extends CustomError {
 constructor(message) {
 super(message, 'my-custom-error', 500_1);
 }
}
</code></pre>
Throw error like
<pre><code>throw new MyCustomError('Something is wrong with your API');
</code></pre>
Output (in Postman)
<pre><code>{
 &quot;status&quot;: &quot;Failed&quot;,
 &quot;code&quot;: 500_1
 &quot;detail&quot;: &quot;Something is wrong with your API&quot;,
code
}
</code></pre>

Let say if I throw GeneralError when call a service, how to make error object like what I want:

<pre><code>{
"status": "Failed",
"code": "500_1",
"detail": "Something is wrong with your API"
} 
</code></pre>

I already try add this on error hook

<pre><code>hook =&gt; {
hook.error = {
"status": "Failed",
"code": "500_1",
"detail": "Something is wrong with your API"
} 
return hook
}
</code></pre>

But still cannot, and still return default error object of feathers: 

<pre><code>{
 "name": "GeneralError",
 "message": "Error",
 "code": 500,
 "className": "general-error",
 "data": {},
 "errors": {}
}
</code></pre>
