How to Catch Bad JSON Request Payload in REST using WCF3.5

Question

Hi,

Since no one replied to my thread in microsoft forum, I'm posting this question here.

I'm using WCF 3.5 REST with JSON output. If I send the below request body

{"persons": [{"fname":"John"}, {"fname":"sheena"}}

to my web API, my REST service throws "500 - Internal Server Error".

If you look at carefully, request is missing the ending square bracket & hence the error comes.

Now, I would like to know how to catch this error??? So, far I've no luck in catching this error at all. I need to give 400 Bad Request error instead. How do I do that?

Thanks!
