Visual Studio 2022中RDLC子报表无法被检测到的问题求助

我现在正尝试用Visual Studio 2022创建RDLC报表，但遇到了个麻烦——每次运行程序都会弹出错误：

The subreport 'foo' could not be found at the specified location bar. Please verify that the subreport has been published and that the name is correct

我查了好多地方，大家都只说在子报表属性面板里填名字就行，根本没人提要先发布子报表这回事。

更新：

我做了几次测试后发现了这个警告，不确定有没有帮助：

Warning: An error occurred while executing the subreport 'RunDetailsSubReport' (Instance: 0): The report definition for report 'RunDetails' has not been specified (rsErrorExecutingSubreport)
