Siddhi Kafka Connection

[programmedrn]

Description:

I'm Using siddhi-tooling-5.1.2,
and trying to connect to kafka via web editor on chrome.

and this is my code,

`@App:name('KakfaUiSample')
@app:description('Receives events via simulation and publish them to a kafka topic in json format')

@sink(type = 'log',
@Map(type = 'json', validate.json = "true"))
define stream pm25LimitedStream(time string, pm25 double);
--Send events to kafka_json_topic

@source(type = 'kafka', bootstrap.servers = "kafka109:9092", topic.list = "airmap4", group.id = "SiddhiUiKafka", threading.option = "single.thread", enable.offsets.commit="true",
@Map(type = 'json'))
define stream KafkaAirmapStream (ts string, svcCode string, svcTgtSeq string, spotDevSeq string, groupTagCd string, occDt string, deviceModelId string, pm10 float, pm25 float, triOxygen float);

@info(name = 'pm25Limitation')
from KafkaAirmapStream
select ts as time, pm25
having pm25 > 70
order by time ASC
insert into pm25LimitedStream;
It works at the first time, and then I stopped to optimize some values, and then it started to give me an errors, saying
[2023-06-08_18-26-51_768] ERROR {io.siddhi.extension.io.kafka.source.ConsumerKafkaGroup} - Error while creating KafkaConsumerThread for topic(s): [airmap4]

and my kafka version is 2.13
I'm using java11
What I can't understand is the above code works some time, but not often.
How can I deal with this isseu?
