Unable to use Airflow variable with function in Jinja template

Question

I'm trying to pass Airflow logical_date to dbt model so that I can use it in the model (sql). I'm using Airflow 2.11.0. I'm doing below, but the dag couldn't get constructed, with an error says:

'logical_date' is undefined.

However it works if I remove the in_timezone conversion. How should I do this? It works in earlier version of Airflow. Thanks.

dbt_task = DbtTaskGroup (
       select = ["mymodel"]
       operator_args{
          "vars": {
                 "logical_date_to_use_in_model" : "{{logical_date.in_timezone('America/Vancouver')}}"
                 },
       },
)

Could you post the following output from python?print(logical_date.in_timezone('America/Vancouver')) — Charalamm

Not sure what parent operator you're using, but the issue is likely because the operator isn't aware that operator_args is a template field and contains Jinja templates. To fix this, you should either:

Declare operator_args explicitly as a template_field, or
Assign operator_args to a variable that is already listed as a template_field.

For example, if you're inheriting from KubernetesPodOperator, its template_fields include things like 'image', 'name', 'cmds', 'arguments', etc. So, you could pass operator_args into the arguments field

self.arguments = {**operator_args} #JUST AN EXAMPLE

when calling super(), which would allow the base operator to handle the templating properly.

thanks. I added template_fields = ("operator_args",) to the operator class, but it still has the same error. Is it how to do option 1? Or anything else that I need to do to declare it as template_fields?

pay attention you not ovveridde your template_fields in the parent operator, just check what fileds are in you parent operator and merge you on variable to it llike i show in the example. if you still getting the error please share the operatore you are using
