index.js:1 Warning: React does not recognize the `endAdornment` prop

I’m getting

index.js:1 Warning: React does not recognize the endAdornmentprop on a DOM element. If you intentionally want it to appear in the DOM as a custom attribute, spell it as lowercaseendadornment instead. If you accidentally passed it from a parent component, remove it from the DOM element

<TextField id="create-topic-form-ttl-field" label="Gather answers for" value={Number.isNaN(this.state.ttl) ? '' : this.state.ttl} onChange={this.handleTtlChange} variant="filled" type="number" className={classes.ttlField} inputProps={{ endAdornment: <InputAdornment position="end">days</InputAdornment>, type: 'number', min: 1, max: TPC_SRV_MAX_TTL, step: 1, }} helperText={' '} /> Now using: “@material-ui/core”: “>=4.9.3”,
