我正在研究 avro 模式。当我尝试使用 dotnet Apache.Avro.Tools --version 1.11.0 命令行自动生成 dto 类 (avrogen -s schema.avsc .) 时，我的架构出现了一些解析错误：
Undefined name: record at 'fields[0].type.items.fields[1].type.items.fields[1].type.type'
我的 schema.avsc 是：

我使用 js 编辑器来 console.log ：fields[0].type.items.fields[1].type.items.fields[1].type.type
当我console.log(fields[0].type.items.fields[1].type.items.fields[1].type)
显示时它是记录：
{
type: 'record',
name: 'FacilityServiceID',
doc: 'Facility Service ID\n' +
'\n' +
' Service at physical facility.\n' +
'\n' +
' @field entity_id: entity id of this facility service\n' +
' @field entity_type: entity type of this facility service. Allowing null values for Small Parcel scenarios\n' +
' (carrier hubs and stations)\n' +
' @field agent_service_type: for facility service with entity_type of agent, the agent_service_type of the\n' +
' entity',
fields: [
{ name: 'entity_id', type: 'int' },
{ name: 'entity_type', type: [Array] },
{ name: 'agent_service_type', type: [Array] }
],
logicalType: 'referentialkey_check',
keyspace: 'facility_service'
}
不知道我的架构有什么问题，并且所有代码都使用avro 查看器进行了很好的处理，有人 可以帮我解决这个错误吗？太感谢了！
