Send All Results for Looker Scheduled Dashboard

Hi, I am trying to use sendAllResults option in Looker Scheduled Plan API, to make it send All results and don’t apply limits to underlying queries, what I am getting in response is confusing:

when sendAllResults = true, getting execption:
{
“message”:“Validation Failed”,
“errors”:[
{
“field”:“dashboard_id”,
“code”:“invalid”,
“message”:“Cannot send all results for dashboards”,
“documentation_url”:“http://docs.looker.com/
},
{
“field”:“format”,
“code”:“invalid”,
“message”:“format csv_zip invalid – valid formats for unlimited Dashboard sent as ‘webhook’ are [:txt, :csv, :inline_json, :json, :json_label, :json_detail, :json_detail_lite_stream, :xlsx]”,
“documentation_url”:“http://docs.looker.com/
}
],
“documentation_url”:“http://docs.looker.com/
}

it clearly says: valid formats for unlimited Dashboard sent as ‘webhook’ are…

when trying to set one of “valid” formats, like “csv”, getting exception:
{
“message”:“Validation Failed”,
“errors”:[
{
“field”:“dashboard_id”,
“code”:“invalid”,
“message”:“Cannot send all results for dashboards”,
“documentation_url”:“http://docs.looker.com/
}
],
“documentation_url”:“http://docs.looker.com/
}

So I set “csv” to get unlimited Dashboard, as said in validation exception description, but still getting error. Is it possible to disable limits when sending scheduled dashboard to webhook?
