Trying to figure out why there is a Binding error

ServiceStack
1

I am receiving some errors on an endpoint, that is pushing data from a web hook (Mailgun).

Is there a way to “intercept” the original data that is pushed on the endpoint just to see why the error is thrown? This is only on very limited calls (<0,1%) but just trying to figure out what’s going on here?

Would be nice if I could just log the pushed content in such cases.

If you want to inspect the request yourself you’d need to Buffer the Request first then you can call IRequest.GetRawBodyAsync() to read the request body.

I tried it with IRequiresRequestStream but then I received even more errors.
Although I did not
https://docs.servicestack.net/serialization-deserialization#buffering-the-request-and-response-streams
set the PreRequestFilters. I suppose this is mandatory, but are these then for ALL endpoints?

Inspect the IHttpRequest first so you only set it on which requests you want to buffer.
