控制器方法：

    [HttpPost("$analyze")]
    public async Task<ActionResult<Bundle>> Analyze([FromBody]Parameters parameters)
    {

        return Ok();
    }

输入（Parameters和输出（Bundle）参数是Hl7.Fhir.R4（nuget，source）中包含的对象

此问题通过最新的swashbuckle版本解决了

Answer 2

UseInlineDefinitionsForEnums 的调用在我的案例中帮助消除了类似的 Resolver error at paths...Could not resolve reference:...。

错误是：

Errors

Resolver error at paths./api/v1/Account/IsTenantAvailable.post.responses.200.content.text/plain.schema.properties.state.$ref
Could not resolve reference: Could not resolve pointer: /components/schemas/TenantAvailabilityState does not exist in document
Resolver error at paths./api/v1/Account/IsTenantAvailable.post.responses.200.content.application/json.schema.properties.state.$ref
Could not resolve reference: Could not resolve pointer: /components/schemas/TenantAvailabilityState does not exist in document
Resolver error at paths./api/v1/Account/IsTenantAvailable.post.responses.200.content.text/json.schema.properties.state.$ref
Could not resolve reference: Could not resolve pointer: /components/schemas/TenantAvailabilityState does not exist in document

引入的调用是：

using Microsoft.Extensions.DependencyInjection;

public class Startup
{
    // ...
    public IServiceProvider ConfigureServices(IServiceCollection services)
    {
        // ...
        services.AddSwaggerGen(options =>
            {
                // ...

                // calling SwaggerGenOptionsExtensions.UseInlineDefinitionsForEnums(Swashbuckle.AspNetCore.SwaggerGen.SwaggerGenOptions) instead of some UseReferencedDefinitionsForEnums
                options.UseInlineDefinitionsForEnums(); // options.UseReferencedDefinitionsForEnums();

                // ...
            }
        // ...
    }
}

插入调用而不是注释掉 UseReferencedDefinitionsForEnums 的调用。由于在我的解决方案中将 aspnetcore 升级到 3.1，它被注释掉了。使用 3.1 的版本只是不再包含此方法，也没有说明应该调用什么。

很明显，这两个调用都与枚举有关。但我不知道它们究竟是什么以及为什么这样做，如果它们是出于相同的目的并且它们是否有任何不良副作用。但它只是在我的许多端点上按“试用”按钮消除屏幕截图中的这个红板的情况下起作用。

我在 5.6.3 的 Swashbuckle.AspNetCore 版本上遇到了这个问题。升级到最新的 6.1.1 没有任何帮助。
