Logstash do not import file

Is Logstash have a limit for max line characters leight?
I have 12 mb json file wich content single line json with multi objects.
Logstash do not work with this file i'am dont know why no error no debug string just status: Successfully started
[INFO ] 2021-01-04 18:29:35.648 [Api Webserver] agent - Successfully started Logstash API endpoint {:port=>9600}
and thats all.
logstash config is ok. i am tested it by spliting original json line by 3357 charecter and it work perfect but if i use my original 12mb file 12463152 charecter nothig happens.
cpu load less than 5%

my logstash config:

input {
  file {
      path => ["/tmp/multi_valid.json"] #OK work
#    path => ["/home/pumba/change/all-items-2020-07-01.log"]
    start_position => "beginning"
    sincedb_path => ["/dev/null"]
    codec => "json"
  }
}

filter {
split { field => "[data]" }
#split { field => "[jobs][builds]" }

}

output {
#  elasticsearch {
#    hosts => ["http://localhost:9200"]
#   index => "setlogs-%{+YYYY.MM.dd}"
#  }
# 
	file {
		path => ["/tmp/logstash_output.txt"]
		}
  stdout {
	codec => rubydebug
  }
}

My original big file is exactly as litle sample but with more characters. Original big file was validate by jsonlint-php and get no error.

Please help i dont know what to do with this.

Does this single line have a newline character in the end? The file input needs a newline to consume the events.

Try to add an empty line after your single big line and see if it works.

You are awesome thanks !!! its work!!!
