Input as file path in logstash config didn't work - elasticsearch

Question

When I run a command like this(on a Windows System):
logstash -f logstash-apache.conf
there's no output and it didn't store any log to the elasticsearch.
so I think it didn't work.
btw I refered to the website:https://www.elastic.co/guide/en/logstash/current/config-examples.html#config-examples
this is my conf file(logstash-apache.conf):
input {
file {
path => ["C:/Users/User/Downloads/logstash-5.5.1/bin/access_log.txt"]
start_position => "beginning"
}
}
filter {
if [path] =~ "access" {
mutate { replace => { "type" => "apache_access" } }
grok {
match => { "message" => "%{COMBINEDAPACHELOG}" }
}
}
date {
match => [ "timestamp" , "dd/MMM/yyyy:HH:mm:ss Z" ]
}
}
output {
elasticsearch {
hosts => ["localhost:9200"]
}
stdout { codec => rubydebug }
}
this is the output:
C:\Users\User\Downloads\logstash-5.5.1\bin>logstash -f logstash-apache.conf
