You should do it this way:

onOfficeChange(e){
   this.setState({addOfficeObj:{name: e.target.value}})
}

You can do it like this:

onOfficeChange(e){
   this.setState({
     addOfficeObj: {
       name: e.target.value
     }
   })
 }

Try this, this should work

onOfficeChange(e){
   let addOfficeObj= this.state.addOfficeObj;
   addOfficeObj.name = e.target.value;
   this.setState({
                    addOfficeObj
                })
 }

You can try this.

onOfficeChange(e){
this.setState(prevState => {
  let addOfficeObj = Object.assign({}, prevState.name); 
  addOfficeObj.name = e.target.value; 
  return { addOfficeObj }; 
})
}

Doing a shallow copy of the top level is not sufficient - the nestedState object should be copied as well.

this.state= {
  addOfficeObj: {
  name: ''
  }
}
onOfficeChange = (e) => {
 this.setState(prevState => ({
    addOfficeObj: {                   // object that we want to update
        ...prevState.addOfficeObj,    // keep all other key-value pairs
        name:  e.target.value         // update the value of specific key
     }
   }))
}

You can do it this way with spread operator , and immutability also remains,(in case you want it )
