And another unexpected behaviour:
```data class Test(val name: Int)```
you declare in meta :
```receiving(Body.auto&lt;Test&gt;().toLens() to Test(3))```
you call in a curl with `-d "{\"name\":5}"` it passes (it’s ok is just for reference of a correct call) but you call also with a bad keyname ex: `-d "{\"ne\":5}"` the call is valid.
if name is a String this works as expected, fails if the key is spelled bad.
I don’t use that value so don’t know if the created object would be valid. I’ll try to make a full test tomorrow evening too late for that right now.

This is down to the Jackson configuration for failing on unexpected keys.

You should get a 400 for the second case. Regardless it’s all in Jackson’s hands here - we’re just delegating to it to unmarshall
