Ansible tasks after delegate_to:127.0.0.1 are skipped - linux

Question

My code is as below, I am reading from a local csv file use those values for tasks on remote hosts
---
- name: Empty Topics
hosts: remote_host
gather_facts: no
vars:
kafka_topics: /bin/kafka-topics
bootstrap_server: "list_of_broker_hosts"
retention_ms: 604800000
command_config: /etc/kafka/client.properties
kafka_log_dirs: /usr/bin/kafka-log-dirs
#ansible_connection: ssh
#ansible_user: ansible
#ansible_become: true
tasks:
- name: "Reading Topic Names"
read_csv:
path: topics_list.csv
register: topics
delegate_to: 127.0.0.1
- name: "Setting Topic Retention to 0"
become: yes
become_user: root
shell:
{{ kafka_topics }} --bootstrap_server {{bootstrap_server}} --alter --topic "{{ item.topic_name }}" --config retention.ms=0 --command_config #{{command_config}}
#touch /tmp/producer_test_1
loop: "{{ topics.list }}"
- name: "waiting for size to go zero "
become: yes
become_user: root
shell:
topic_size=1
while [ $topic_size -ne 0 ]
do
topic_size=`{{kafka_log_dirs}} --command_config {{command_config}} --bootstrap_server {{bootstrap_server}} --topic-list "{{ item.topic_name }}" --describe | grep -oP '(?<=size":)\d+' | awk '{ sum += $1 } END { print sum }' `
sleep 40
done
loop: "{{ topics.list }}"
- name : "Setting Topic Retention to 7"
become: yes
become_user: root
shell:
#{{ kafka_topics }} --bootstrap_server {{bootstrap_server}} --alter --topic "{{ item.topic_name }}" --config retention.ms={{retention_ms}} --command_config {{command_config}}
#touch /tmp/producer_test_2
loop: "{{ topics.list }}"
here the tasks after first task "Reading Topic Names" are skipped , if I remove this task, they succeed but that means I have to hard code values on subsequent tasks
execution log as below. How can I avoid this. current ansible version is 2.9.19 This playbook had previously worked as is on ansible version 2.9.6 in my previous organization, not sure what settings may be changed in my new company.
I tried delegate_to: localhost as well as delegate_to: 127:0:0:1

As suggested by β.εηοιτ.βε, I checked the csv file, although there were contents , it was missing the header row, hence the issue. Now with header row added to the csv file, the code works.
