Can't setState inside onChange function

[katp4]

Hello,

I'm trying to use this but i'm getting an irrational error. First of all, setting the state of anything throws the below errors (see screenshots) and even if that works, i'm unable to use the "value" property to make it a controlled input as it somehow picks it up itself. i would appreciate your input.

@material-ui/core "version": "3.9.0"
react "version": "16.7.0"

Please see my code below;

<FormControl fullWidth={true} className={classes.formControl}>
                                            <InputLabel className={classes.formControl} htmlFor="phoneNumber">Phone
                                                Number
                                            </InputLabel>
                                            <ReactPhoneInput
                                                regions={["europe", "oceania"]}
                                                name="phone"
                                                onChange={this.handleOnChange.bind(this)}
                                                required={true}
                                            />
                                            <Typography align="left" paragraph={true} variant="subtitle2" color="textPrimary" className={classes.smallBlueFont}>{this.state.errors.phone}</Typography>
                                        </FormControl>

where handleOnChange is

handleOnChange(countryCode, value) {
         console.log(1,value, countryCode)

         this.setState({ anything: true})

     }

Hi @katp4 sorry for the delay in getting to this - is this still an issue or were you able to fix it?
