Airflow secure-file-priv option - cannot insert data from file to database - airflow

Question

I have a DAG of three tasks. The first one checks if csv file exists, the second creates MySQL table and the third one inserts the data from csv file into MySQL table. First two tasks succeed but the last one not saying that due to secure-file-priv option I have no rigts to insert data from file to database.
default_args = {
"owner": "airflow",
"start_date": airflow.utils.dates.days_ago(1),
"retries": 1,
"retry_delay": timedelta(seconds=5)
}
with DAG('sql_operator_from_csv_to_mysql',default_args=default_args,schedule_interval='#daily', template_searchpath=['/opt/airflow/sql_files_mysql'], catchup=True) as dag:
t1 = BashOperator(task_id='check_file_exists', bash_command='ls /opt/airflow/store_files/students_data.csv | sha1sum', retries=2, retry_delay=timedelta(seconds=15))
t2 = MySqlOperator(task_id='create_mysql_table', mysql_conn_id="mysql_conn", sql="create_table.sql")
t3 = MySqlOperator(task_id='insert_into_table', mysql_conn_id="mysql_conn", sql="insert_into_table.sql")
SQL statement:
LOAD DATA INFILE '/store_files/students_data.csv' INTO TABLE students_db FIELDS TERMINATED BY ',' LINES TERMINATED BY '\n' IGNORE 1 ROWS;
mysql.cnf file is as following.
!includedir /etc/mysql/conf.d/
!includedir /etc/mysql/mysql.conf.d/
[mysqld]
pid-file = /var/run/mysqld/mysqld.pid
socket = /var/run/mysqld/mysqld.sock
datadir = /var/lib/mysql
secure-file-priv= ""
I have tried to mark 'secure-file-priv' option as an empty string and showing the location of a csv file but none of them are working.
secure-file-priv= ""
secure-file-priv= "/opt/airflow/store_files"
Error message saying:

Any ideas to solve this problem?

I have tried to make some minor modifications in the docker-compose.yaml file.
