I using filter array to filter data as output below:
[
{
"@odata.etag": "",
"ItemInternalId": "0262cbd9-6c2c-",
"sku_num": "709-BBFE ",
"item_short_name": "CH",
"service_level_code": "AB",
"SL_Update_Dts": "0.6",
}
]
then we want to display "item_short_name" value as output but getting above error
output expression: concat(first(body('Filter_array'))['item_short_name'])
