When using KV in logstash, I am getting my key with escaped character, how do i read this value in the Ruby?

[mastersmit (Smit)]

I have data coming from Kafka, and the data will look like this:

   "x-vcap-request-id":"smitshah",
   "x-cf-applicationid":"test",
   "x-cf-instanceid":"test2",
   "sec-ch-ua":"\"something\";\"willwork\""

It is similiar to JSON but it is not. So i thought of using KV filter,

kv {
 source => "header_v1"
value_split => ":"
field_split => ","
}

But now i am getting key this way:

So when i do event.get('\"x-vcap-request-id\"') but i am getting empty result.

How can i resolve this?

I used the below which solved the problem:

kv {
        remove_char_key => "\""
}
