I have a javascript error in react js project

I've tried many things and there's no way, always appears this error I tried to use only one option to see if passed, changed the call of jquery, but not.
I looked in various places on the internet about this error, but could not solve or understand why it is happening.

React native invariant violation: text strings must be rendered within a <Text> component in a form (TextField)

This is my code for a form in React Native which is where i seem to be getting the error. I'm confused as this renders perfectly fine in my web simulator (expo):
working form but I get this error when I use ios simulator. I don't have any conditional logic or spaces/semicolons(at least what i can find) so not sure why I'm getting this error, also i'm using material ui core for my text fields in my form (which is where the error is supposedly coming from if you ref the image above). Any help would be appreciated!! pls help

You cannot use #material-ui/core for React Native projects.
#material-ui/core can work for expo because it's web based. But I'm pretty sure that it won't work for native environments.
I'd like to recommend alternatives, but I don't use material design for React Native because it simply doesn't fit to iOS.

It's related to server side rendering and client side rendering.
As Next.js provides SSR, you need to consider using objects like window, localStorage and so on. While compiling client side, those objects are fine but when Nextjs compiles server side, it shows error like you shared.
It seems like GoogleLogin uses window object if you assign the client id. You need to check that first. And lemme know the result.

Hey the easy way for Material UI Components, to rendered it on Next js framework.Just use component to render it on client side only.
(If any component use Window object on server side it will show this error)
solution:
import NoSsr from '#material-ui/core/NoSsr';
<NoSsr>
<MicrosoftLogin
clientId="a973536f-eb3e-4fd9-9394-9f4194d69153"
authCallback={authHandler}
redirectUri="https://localhost:3000/"
className={classes.winIcon}
children={
<IconButton>
<Icon className="fab fa-windows" color="primary" />
</IconButton>
}
/>
</NoSsr>

Date not updated (handleDateChange) in React Hooks using material-ui-picker

Below is the functional signup component in React. I have one particular problem with the DatePicker component. It renders correctly on the sign up form. When I click on the submit button, it does not give me the selected date but instead it sends me the initial state of the component. Other states such as fullname, password and email are updated accordingly.
To prove that the date was not updated, I tried putting "null" in the useState() and when I get the result in the database, as expected the date is of a "null" type. How do I update the initial state to the updated state?

I am trying to add the Material-UI InfoIcon into my code. But I don't know how to implement it in TextField

I am trying to add the Material-UI InfoIcon--> into my code. But I don't know how to implement it in TextField.
Here is the material-UI code:
<InfoIcon fontSize="small" />
Here is where I want it to be:
<Grid item xs={5}>
<TextField
id="createdate"
label="Create Date"
value={dateCheck(workOrderDetail.reported_date, 'll') }
variant="filled"
disabled
fullWidth
inputProps={{ style: style.textFieldInput }}
/>
</Grid>

You should put your icon with InputAdornment component. I have create a quick demo for you:
import InputAdornment from '#material-ui/core/InputAdornment';
import TextField from '#material-ui/core/TextField';
import Grid from '#material-ui/core/Grid';
import InfoIcon from '#material-ui/icons/InfoIcon';
<TextField
id="createdate"
label="Create Date"
value={dateCheck(workOrderDetail.reported_date, 'll') }
variant="filled"
disabled
fullWidth
InputProps={{
style: style.textFieldInput,
startAdornment: (
<InputAdornment position="start">
<AccountCircle />
</InputAdornment>
),
}}
/>
Reference: React, Material-UI Documentation, input fields

So here is what I did to make the styling correct.
I made a function:
const label = () => {
return (
<React.Fragment>
Create Date <InfoIcon fontSize='small'></InfoIcon>
</React.Fragment>
)
}
<Grid item xs={5}>
<TextField
id="createdate"
label={label()}
value={dateCheck(workOrderDetail.reported_date, 'll') }
inputProps={{ style: style.textFieldInput }}
variant="filled"
disabled
fullWidth
/>
</Grid>
