Also check if the URL if derived has query parameters encoded. You usually get url invalid error but you can check for this
1. ${response.http.allheadervalues}
2. ${response.mainpart}
Finally look in you backend logs you might get some exception

Subject: httpRouting.reasonCode = {Integer} "-5"
On a Route via HTTP assertion the below reason code is return which by help documentation states:
Undefined | An unknown type of error has occurred (for example, an invalid response). |
- httpRouting.reasonCode = {Integer} "-5"
Is there anything that can be done to help determine the root cause of the error?
