问题

我如何从GraphQL查询枚举。我正在使用Nest.js和GraphQL，并且出现错误："message": "Enum "TraitReportType" cannot represent value: "EMBEDDED"。",
我尝试使用type: EMBEDDED，但不起作用。还尝试使用try {}，但在子选择中也不起作用。

这是我的类型：@Expose()
@IsDefined()
@IsEnum(TraitReportType)
@ApiProperty({ enum: TraitReportType })
@Field(() => TraitReportType, { nullable: false })
type: TraitReportType;

进一步的TraitReportType：import { registerEnumType } from '@nestjs/graphql';

export enum TraitReportType {
	LAYOUT = 'layout',
	EMBEDDED = 'embedded',
}

registerEnumType(TraitReportType, {
	name: 'TraitReportType',
	description: 'Trait Report Type枚举类型',
});

我如何查询：
query EntityReportsQuery($id: ID!) {
entity(id: $id) {
id
secondaryId
reports {
key
name
description
icon {
type
component
name
size
source
}
type
layout
url
}
}
}

我从数据库查询的数据是：
{
"key": "A",
"url": "https://search.mevris.app/s/app-dashboards/app/dashboards#/view/204e17a0-a6df-11ed-ac80-b52d3b051a25?embed=true&_g=(filters:!(('$state':(store:globalState),meta:(alias:!n,disabled:!f,key:entityId.keyword,negate:!f,params:(query:%2203258d26-3914-4a19-b919-f8e88f3a68dd%22),type:phrase),query:(match_phrase:(entityId:%22${id}%22)))),refreshInterval:(pause:!t,value:0),time:(from:now-15m,to:now))&show-time-filter=true&hide-filter-bar=true",
"icon": {
"name": "current-ac",
"size": 2.7,
"type": "type icon",
"component": "component"
},
"name": "Current",
"type": "EMBEDDED",
"description": "Sum of Current"
}

我尝试使用type: EMBEDDED，但不起作用。

how can i query enum from graphql . i am using nest.js with graphql

i try with type:EMBEEDED but did not works .  also try with try {} also did not work with sub selection .

here is my type : @Expose()
@IsDefined()
@IsEnum(TraitReportType)
@ApiProperty({ enum: TraitReportType })
@Field(() => TraitReportType, { nullable: false })
type: TraitReportType;

further TraitReportType : import { registerEnumType } from '@nestjs/graphql';

export enum TraitReportType {
LAYOUT = 'layout',
EMBEDDED = 'embedded',
}

registerEnumType(TraitReportType, {
name: 'TraitReportType',
description: 'Trait Report Type enum types',
});

how i query : query EntityReportsQuery($id: ID!) {
entity(id: $id) {
id
secondaryId
reports {
key
name
description
icon {
type
component
name
size
source
}
type
layout
url
}
}
} and data which i query from db is : {
"key": "A",
"url": "https://search.mevris.app/s/app-dashboards/app/dashboards#/view/204e17a0-a6df-11ed-ac80-b52d3b051a25?embed=true&_g=(filters:!(('$state':(store:globalState),meta:(alias:!n,disabled:!f,key:entityId.keyword,negate:!f,params:(query:%2203258d26-3914-4a19-b919-f8e88f3a68dd%22),type:phrase),query:(match_phrase:(entityId:%22${id}%22)))),refreshInterval:(pause:!t,value:0),time:(from:now-15m,to:now))&show-time-filter=true&hide-filter-bar=true",
"icon": {
"name": "current-ac",

"type": "type icon",
"component": "component"
