Passing Jinja variables in airflow params dict - python-3.x

Question

I am trying to use templated params dict in SnwoflakeOperator. I have 2 tasks one to create a S3 object and then delete and replace the content of the table with s3 object content
execution_date = "{{ execution_date.int_timestamp | int }}" # built in macro
task1 = PythonOperator(task_id='s3_create',
op_kwargs={'s3_key': f'{execution_date}_{file}'})
task_2 = SnowflakeOperator(task_id='load_data',
sql=["""copy into {{params.table}} from {{ params.stage }}
files = ('{{ params.files }}')
file_format = 'csv'
"""]
params={'table':'test_table',
'files'=f'{execution_date}_{file}'}
)
task_1 >> task_2
It is not rendering as expected and have tried almost all formatting combinations.
Note: I cannot use S3ToSnowflakeOperator as I have do more than just copying the contents into the table.

sql is templated filed thus it can automatically render execution_date (since it's Airflow build-in macro) there is no need to set it via params. The params is used to render python variables or just strings that you want to pass.
You can just set it directly as:
file = "test_file.csv"
SnowflakeOperator(
task_id='load_data',
sql=""" copy into {{ params.table }} from {{ params.stage }}
files = ('{{ execution_date }}_{{ params.file }}')
file_format = csv
""",
params={
'table': 'test_table',
'stage': 'test_stage',
'file': file
}
)
It will be rendered as:
I'm not sure this is the file name you wanted but you can change execution_date to any other macro you wish.
Edit:
You can replace {{ execution_date }} with {{ execution_date.int_timestamp | int }} it will produce:
