Iterating through Mongo Collection Using NodeJS and Axios

I'm looking to loop through a collection basically capture the objectID of a property in the "clinics" document I have created. It console.logs the proper objectID but for some reason it isn't running the this.setState and instead errors out saying TypeError: this.setState is not a function. I am not sure what I am doing wrong here - any and all help appreciated!

constructor(props){
    super(props);

    this.onChangeName = this.onChangeName.bind(this);
    this.onChangeEmail = this.onChangeEmail.bind(this);
    this.onChangeDOB = this.onChangeDOB.bind(this)
    this.onChangePhonenumber = this.onChangePhonenumber.bind(this);
    this.onChangeAddress = this.onChangeAddress.bind(this);
    this.onChangeFamilySize = this.onChangeFamilySize.bind(this);
    this.onChangePrescription = this.onChangePrescription.bind(this);
    this.onChangeClinicID = this.onChangeClinicID.bind(this);
    this.onSubmit = this.onSubmit.bind(this);

    this.state = {
        name: '',
        email: '',
        dob: new Date(),
        phonenumber: 0,
        address: '',
        familysize: '',
        prescription: '',
        clinicID: null,
        prescriptions: [],
    }
}


onSubmit(e){
    e.preventDefault();
    
    axios.get('http://localhost:5000/clinics/')
    .then(response => {
        for (var i = 0; i < response.data.length; i++){
            var clinicPrescription = response.data[i].prescription;
            //console.log(clinicPrescription)
            
            var n = clinicPrescription.localeCompare(this.state.prescription);
            if(n == 0){
                console.log(response.data[i]._id)
                this.setState({
                    clinicID: response.data[i]._id
                })
            } 
        
            
        }
    })
    .catch((error) => {
        console.log(error);
    })

    const patient = {
        name: this.state.name,
        email: this.state.email,
        dob: this.state.dob,
        phonenumber: this.state.phonenumber,
        address: this.state.address,
        familysize: this.state.familysize,
        prescription: this.state.prescription,
        clinicID: this.state.clinicID
    }

    console.log(patient)

    axios.post('http://localhost:5000/patients/add', patient)
        .then(res => console.log(res.data));

    this.setState = {
        name: '',
        email: '',
        dob: new Date(),
        phonenumber: 0,
        address: '',
        familysize: '',
        prescription: '',
        clinicID: null,

    }
    
    //window.location = '/matching';
    
}

  const { data } = await axios.post(url, this.exportPatient())

  console.log(data);
}

  e.preventDefault();

  try {
    await setClinicID();
    await addPatient();
  } catch (error) {
    console.log(error);
  }
}

You are overwriting the function this.setState
