Here is my logstash configuration
```
filter {
grok {
match => {
"message" => { '%{DATA:req_id} %{IPV4:host} %{DATA:machine_name} %{DATA:location} %{DATA:zuid} %{DATA:zoid} %{DATA:thread_id} %{DATA:class_name} %{DATA:method} %{DATA:level} %{DATA:timestamp} %{DATA:zl_thread_id} %{DATA:message}' }
}
}
date {
match => ["timestamp" , "dd-MM-yyyy HH:mm:ss Z"]
}
mutate {
remove_field => ["@version" ,"req_id" ,"host" ,"machine_name" ,"location" ,"zuid" ,"zoid" ,"zl_thread_id"] } }
```

The `message` parameter in the grok filter should be a string or a list of strings, so you should not have any curly braces there.

You still have curly braces. Look at the examples in the documentation.
