Material UI, Warning <td> cannot appear as a child of <div> - reactjs

Question

I'm using React, typescript and Material UI. I've created a pretty common "Create user form" with basic inputs for username, name, email, ect. Added two buttons, "Edit" and "Delete." Everything seems to function properly, however, I cannot get this error message resolved.
Warning: validateDOMNesting(...): <td> cannot appear as a child of <div>.
Here's the table from a react component:
<TableContainer className={classes.scroll} component={Paper}>
<Table stickyHeader aria-label="table">
<TableHead>
<TableRow>
<TableCell>Username</TableCell>
<TableCell align="right">First name</TableCell>
<TableCell align="right">Last name</TableCell>
<TableCell align="right">Email</TableCell>
<TableCell align="right">Connect_username</TableCell>
<TableCell align="right">Role</TableCell>
<TableCell align="left">Edit</TableCell>
<TableCell align="left">Delete</TableCell>
</TableRow>
</TableHead>
<TableBody>
{(rowsPerPage > 0
? props?.items.slice(page * rowsPerPage, page * rowsPerPage + rowsPerPage)
: props?.items
).map(item => (
<TableRow key={item.user_id}>
<TableCell component="th">{item.username}</TableCell>
<TableCell align="right">{item.first_name}</TableCell>
<TableCell align="right">{item.last_name}</TableCell>
<TableCell align="right">{item.email}</TableCell>
<TableCell align="right">{item.connect_username}</TableCell>
<TableCell align="right">{item.role?.map(r=>r.role).join(",")}</TableCell>
<TableCell>
<Button onClick={() => props.handleEdit(item)}>Edit</Button>
</TableCell>
<TableCell>
<Button onClick={() => props.handleConfirmDelete(item.user_id)}>Delete</Button>
</TableCell>
</TableRow>
))}
</TableBody>
<TablePagination
rowsPerPageOptions={[10, 25, { label: 'All', value: -1 }]}
count={props.items.length}
rowsPerPage={rowsPerPage}
page={page}
onPageChange={handleChangePage}
onRowsPerPageChange={handleChangeRowsPerPage}
/>
</Table>
</TableContainer>

Answer 1

component={Paper} is likely causing this. Can you try removing it? If you want the table to appear on a Paper component, then try nesting TableContainer under Paper.

Answer 2

put TablePagination in the TableBody tag and wrap it in TableRow.
Had a similar issue and this fixed it.
Like this:
<TableBody>
{(rowsPerPage > 0
? props?.items.slice(page * rowsPerPage, page * rowsPerPage + rowsPerPage)
: props?.items)
.map(item => (
<TableRow key={item.user_id}>
<TableCell component="th">{item.username}</TableCell>
<TableCell align="right">{item.first_name}</TableCell>
<TableCell align="right">{item.last_name}</TableCell>
<TableCell align="right">{item.email}</TableCell>
<TableCell align="right">{item.connect_username}</TableCell>
<TableCell align="right">{item.role?.map(r=>r.role).join(",")}</TableCell>
<TableCell>
<Button onClick={() => props.handleEdit(item)}>
Edit
</Button>
</TableCell>
<TableCell>
<Button onClick={() => props.handleConfirmDelete(item.user_id)}>
Delete
</Button>
</TableCell>
</TableRow>
<TableRow>
<TablePagination
rowsPerPageOptions={[10, 25, { label: 'All', value: -1 }]}
count={props.items.length}
rowsPerPage={rowsPerPage}
page={page}
onPageChange={handleChangePage}
onRowsPerPageChange={handleChangeRowsPerPage}
/>
</TableRow>
))}
</TableBody>

Answer 3

update: "#mui/material": "^5.10.9"
in my case this error was causing TablePagination and not Paper component.
working solution is wrapping pagination not only with row but also footer as follow
<TableContainer component={Paper}>
<Table>
<TableBody>
...
</TableBody>
<TableFooter>
<TableRow>
<TablePagination />
</TableRow>
</TableFooter>
</Table>
</TableContainer>
