I think you need to convert any non-str type into a string to render it in the template, i.e., just str(foo).
https://github.com/apache/incubator-airflow/blob/1d3bb5470711a935b36b6a0ab4c7ec414d460d75/airflow/models.py#L2613 But in your template, if I understand correctly that you're building a JSON object as a string you could render that particular field without quotes wrapping it, so a JSON parser would detect it as an int, not a str. Does that make sense? Can you share your code?
