data task starts the actual import process (and is called by
auto behind the scenes). Unlike
data directly will not cause a redirect to one of the other tasks if any meta input is needed. Instead,
data will attempt to import each record as-is, and report any errors that occured due to e.g. missing fields or unmapped foreign keys.
This is an asynchronous method, and returns a
task_id to be used with the
status API. The default run_data.html template (and corresponding RunData React view) includes a
<progress> element for use with status task.
