Reactjs MUI：在props 主题中找到的值：；错误；是[Object]，而不是字符串或数字

在MUI v5.14.13中，一切运行正常，突然我开始收到以下错误:

MUI: The value found in theme for prop: "error" is an [Object] instead of string or number. Check if you forgot to add the correct dotted notation, eg, "background.paper" instead of "background". 

看起来像是来自style.js:34号档案.尽管该组件中没有直接使用样式化组件，但我收到了上面的错误消息.

Here is an example

下面的代码将全屏启动一个对话框并在单击Cancel时将其关闭:

import * as React from "react";
import Dialog from "@mui/material/Dialog";
import AppBar from "@mui/material/AppBar";
import Toolbar from "@mui/material/Toolbar";
import IconButton from "@mui/material/IconButton";
import CloseIcon from "@mui/icons-material/Close";
import Slide from "@mui/material/Slide";
import { Box, Button, Stack } from "@mui/material";

const Transition = React.forwardRef(function Transition(props, ref) {
  return <Slide direction="up" ref={ref} {...props} />;
});

const FullScreenDialog = ({ open, onClose }) => {
  return (
    <div>
      <Dialog
        fullScreen
        open={open}
        onClose={onClose}
        TransitionComponent={Transition}
      >
        <AppBar sx={{ position: "relative" }}>
          <Toolbar>
            <IconButton
              edge="start"
              color="inherit"
              onClick={onClose}
              aria-label="close"
            >
              <CloseIcon />
            </IconButton>
          </Toolbar>
        </AppBar>
        <Box margin={{ sm: 3, xs: 2 }}>
          <Stack spacing={1} direction="row" justifyContent={"flex-end"}>
            <Button
              variant="outlined"
              color="error"
              size="small"
              onClick={onClose}
              sx={{
                borderRadius: 10,
                textTransform: "none",
                ":hover": {
                  bgcolor: "error",
                  color: "error",
                  border: "error",
                },
              }}
            >
              Cancel
            </Button>
          </Stack>
        </Box>
      </Dialog>
    </div>
  );
};

export default FullScreenDialog;

当点击Cancel按钮时，同样的错误也会出现.即使从不同的组件单击Start按钮，也会出现相同的错误.

您认为MUI中有什么变化是导致此问题的原因吗？
