# Invalid Custom Route `source`
|
|
|
|
#### Why This Error Occurred
|
|
|
|
When defining custom routes a route was added that causes an error during parsing. This can be due to trying to use normal `RegExp` syntax like negative lookaheads (`?!exclude`) without following `path-to-regexp`'s syntax for it.
|
|
|
|
#### Possible Ways to Fix It
|
|
|
|
Wrap the `RegExp` part of your `source` as an un-named parameter.
|
|
|
|
**Before**
|
|
|
|
```js
|
|
{
|
|
source: '/feedback/(?!general)',
|
|
destination: '/feedback/general'
|
|
}
|
|
```
|
|
|
|
**After**
|
|
|
|
```js
|
|
{
|
|
source: '/feedback/((?!general).*)',
|
|
destination: '/feedback/general'
|
|
}
|
|
```
