Module template 

The substitution language of a parameter string. A reference is written between {{ and }}, and the language is substitution only.

The references:

• {{ partition }}, the partition of the task instance.
• {{ run.<field> }}, a field of the run: id, the run id of the task instance, or summary, the summary of the graph run as JSON text.
• {{ upstream.<node>.<path> }}, the output of an upstream node, or the value at a dotted path into it.
• {{ env.<NAME> }}, an environment variable of the process that renders the template.

A reference to an unset variable fails the task instance. The error of a failed http request includes the URL.
