Hi,

i’m trying to create a new item in a board with populated columns using postman.

however when i submit the following mutation query as per the APIs guide, i keep getting the following error:{“error_message”:“Internal server error”,“status_code”:500}

i have tried to send it in different variations.

i did manage to create a simle item with no populated columns.

this is the query i use in postman:

mutation ($boardId: Int!, $itemName: String!, $columnValues: JSON!)

{

create_item 



(board_id: $boardId, item_name: $itemName, column_values: $columnValues) 



 {id}

}

**with the following graphql variables: **

{

"boardId": 1201957991,



"itemName" : "229",

“columnValues” : {

"name": "ido",



"address" : "PTV",



"phone" : "0504441814",



"order_date" : {"date" : "2021-04-11"},



"model" : "Marumba",



"__units" : 300



}

}

please find also screenshot attached:

your help will be much appreciated
