Expect: 100-continue header corrupted

[annaku_rad]

I'm testing my API-Proxy and when I'm sending in the request (using curl) the 'Expect: 100-continue' header, I see in the JavaScript policy in the

request.headers

that I'm getting- the header becomes "xxpect":"100-continue" in the Proxy.

I see clearly in curl that what's sent is > Expect: 100-continue.

Could you suggest why could this happen? Thanks
