Hey there, can any help me resolve this problem,  
I am parsing Cloudflare audit logs via its API, I am putting here my code chunk of ` .conf` file for Logstash plugin `input,filter and output`. Also, attaching a error screenshot at the end of the message.

**I understand it is a regex error, but I want to understand if there is any way I can pass "-" (hyphen).**

```
# The # character at the beginning of a line indicates a comment. Use
# comments to describe your configuration.
input {
        http_poller
        {
                urls => {
                        method => "GET"
                        cloudflare => " https://api.cloudflare.com/client/v4/user/audit_logs"
                {
                    headers => {
                        X-Auth-Email => "email@redacted.com"
                        X-Auth-Key => "api_key"
                        Content-Type => "application/json"
                    }
                }
                }
        }
}
# optional.
filter {
        json
        {
            source => "message"
        }
}
output {
        stdout { codec => rubydebug }
}

```

Surround your header names with double quotes.

I changed it with double quotes, Now it is giving  
`[FATAL] 2020-11-10 06:32:38.962 [LogStash::Runner] runner - The given configuration is invalid. Reason: undefined method get for #<Java::OrgLogstashConfigIrImperative::PluginStatement:0x3108d1e1>`

I tried to run with --config.debug for detailed error message.

```
