HTTP Headers response Logstash http filter

Hello!
I am trying to use logstash's http filter to get some data from apis.

One of the most important values is received as a header and yet logstash is not showing me all the headers. Including those that have the same name and it is only showing 1 of them.

Could someone tell me if there is a way to increase the verbose or show all the fields ?

Thanks in advance!
