Who used woocomerce rest api command batch processing not working?

Question

WooCommerce

I use rest api woocomerce. Everything seems to be fine, but batch requests do not work.
Maybe something is not included. Or I do not understand something?

Client application 1s 7.7 on it I will shy away HTTP requests. Everything works correctly creating one element, getting lists of elements except for one batch input.
Command = /wp-json/wc/v3/products/batch;

Request Body =

{"create":[
{
"name":"1 сорт Брус дверной коробки 34*70*21-10 Итал. орех",
"type":"simple",
"status":"publish",
"featured":false, 
"catalog_visibility":"visible",
"sku":"",
"regular_price":"150.00",
"virtual":false,
"downloadable":false,
"tax_status":"none",
"manage_stock":true
},
{
"name":"102/34 Плита потолочная *38",
"type":"simple",
"status":"publish",
"featured":false, 
"catalog_visibility":"visible",
"sku":"",
"regular_price":"150.00",
"virtual":false,
"downloadable":false,
"tax_status":"none",
"manage_stock":true
}]}

Server response:
HTTP 500 INTERNAL SERVER ERROR

Any thoughts?
