大家好，

在最近的一些 Discourse 更新后，我注意到帖子中的媒体上传出现了一个错误。它仅发生在本地上传时，而不是热链接。

我在 app.yml 中设置了 upload\_size: 30m。在 Discourse 设置中：  
files.max image size kb - 4 Mb  
files.max attachment size kb - 20 Mb。

这些设置多年来一直对我来说很好。

日志中的错误消息如下所示：

Discourse 安全模式或 launcher rebuild 都没有帮到我。如何解决这个问题？

提前感谢。

此问题已创建修复程序

> <https://github.com/discourse/discourse/pull/24947>
>
> Settings that are using the new \`file\_size\_restriction\` types like the
> \`max\_imag…e\_size\_kb\` setting need to have their values saved as integers.
> This was a recent regression in 00209f03e6bc55c6dd776dbe828b8bb53cd935f4
> that caused these values to be saved as strings.
> 
> This change also removes negatives from the validation regex because
> file sizes can't be negative anyways.

如果您拉取最新代码并重新构建，现在应该可以正常工作。请告知我们进展情况。
