“name”: “projects/make-/databases/(default)/documents/users/i1F1pUS5bGY9P7ZHVECD”,
“fields”: {
“email”: {
“stringValue”: “19D”
},
“nickname”: {
“stringValue”: “kalam”
},
“surname”: {
“stringValue”: “vam”
},
“name”: {
“stringValue”: “dim”
},
“phonenum”: {
“stringValue”: “69409”
}
},
“createTime”: “2021-12-18T14:46:18.749260Z”,
“updateTime”: “2021-12-22T19:13:49.909510Z”
