Volo.Abp.AbpException: No theme registered! Use AbpThemingOptions to register themes

[ZhaoYis]

I have an ABP webapi project that debugs locally and does not throw an exception. After the project is published to IIS, it throws an exception, but I do not use the UI module.How can I set it to run the project normally
The error message is as follows:

• Your ABP Framework version.
• Your User Interface type (Angular/MVC/React... etc.) if the issue is related to a specific UI
• Exception message and stack trace if available (check the logs).
• Steps needed to reproduce the problem.

[ZhaoYis]

Hi.

• ABP Framework Version：3.3.1
• No UI, just a web API project
• Local debugging can run normally. This error occurs when I deploy the project to IIS through the publishing function of vs.
  use release configuration
  

[maliming]

You can try to use dotnet publish command.

I have same the problem. Did you solve it? @ZhaoYis

[GeassAce]

I solved the problem, it caused by that, @ZhaoYis

` if (env.IsDevelopment())-----> clear it when U publish in iis
{
app.UseSwagger();
app.UseAbpSwaggerUI(options =>
{
// 遍历分组信息，生成Json
SwaggerSetting.ApiInfos.ForEach(x =>
{
options.SwaggerEndpoint($"/swagger/{x.UrlPrefix}/swagger.json", x.Name);
});

                // 模型的默认扩展深度，设置为 -1 完全隐藏模型
                options.DefaultModelsExpandDepth(-1);
                // API文档仅展开标记
                options.DocExpansion(DocExpansion.List);
                // API前缀设置为空
                //options.RoutePrefix = string.Empty;
                // API页面Title
                options.DocumentTitle = "接口文档 - SPSI";

                //options.SwaggerEndpoint("/swagger/v1/swagger.json", "Support APP API");

                var configuration = context.GetConfiguration();
                options.OAuthClientId(configuration["AuthServer:SwaggerClientId"]);
                options.OAuthClientSecret(configuration["AuthServer:SwaggerClientSecret"]);

            });
        }`

[hatami57]

for me, it's because of this lines (I use the app as WebApi so it does not need to ErrorPage UI):

if (!env.IsDevelopment())
{
    app.UseErrorPage();
}

To solve the problem, remove or comment these lines.

add code typeof(AbpAspNetCoreMvcUiBasicThemeModule)
