Hi,

I’m not sure but in the documentation(REST API :: Jmix Documentation) the element ‘entities’ is never mentioned so my guess would be that your REST request body should not contain entities but :

[
{
    "id": "cb090350-2694-e2bb-f5d9-813daa8dc418", 
    "name": "booksAvailability(xlsx)",
    "code": "BOOKS_AVAIL",
    "group": "4e083530-0b9c-11e1-9b41-6bdaa41bff94"
},
{
    "id": "d8c7f4c5-2dd7-c7f1-7286-f8dd286d2603",
    "name": "LiteratureTypes(csv)",
    "group": "4e083530-0b9c-11e1-9b41-6bdaa41bff94"
}

]
json

- report ID,
- report name,
- report system code (if exists),
- group ID.
