I am using Logstash 6.5. I want to read the JSON file, process it and end the execution of Logstash. The format of the input file is similar to the following:

```auto
[
{
    "id":"1",
    "value":"v1"
},
{
    "id":"2",
    "value":"v2"
},
{
    "id":"3",
    "value":"v3"
}
]

```

So basically it's an array with JSON structures.  
I have made a simple configuration script:

```auto
input {
    file {
        type => "json"
        path => "C:/logstash-6.5.1/datatest_struct_array.json"
        start_position => "beginning"
        sincedb_path => "nil"
        }
}
filter {
}
output {
    stdout { codec => rubydebug }  
}

```

When I invoke Logstash with that config basically nothing happens. It just hangs on the following log message  
`[INFO][logstash.agent] Successfully started Logstash API endpoint {:port=>9600}`  
and does nothing. No error, no output.  
I tried also `\` instead of `/` in the file name, but nothing changes.

Your sincedb\_path should "NUL", not "nil".

I fixed that, but nothing changed. No error, no output.
