how can i fix 0 arguments, but got 1 problem when using the redux toolkit create actions in reactjs

Question

i've been trying to implement a redux store using redux toolkit in reactjs , but i've been getting this error

Calling this redux#ActionCreator with an argument will return a PayloadAction of type T with a payload of P

Expected 0 arguments, but got 1.

this is my prject slice projectSlice.js where i create my slice , reducer and actions using the redux toolkit

import { createSlice , PayloadAction } from "@reduxjs/toolkit";
export const projectSlice = createSlice({
    name : "project" ,
    initialState : {
        fullProject : {
            selectedProject : null,
            documents : null ,
            collaborators : null ,
            meetings : null ,
            remarks : null ,
            observations : null,
            projectSelected : null,

        }
    
    },
    reducers : {
        addProject : (state , action  ) => {

            state.fullProject.selectedProject = action.payload

        },
        selectFirstProject : (state , action  ) => {

            state.fullProject.projectSelected = action.payload

        }
    }
})


export const {  selectFirstProject } = projectSlice.actions;
export const { addProject } = projectSlice.actions;
export const selectFullProject = (state) => state.project.fullProject;


export default projectSlice.reducer;

and this is how i dispatch the action to redux inside a promise function

 function  promise   ()  {

        // SEND REQUEST TO ADD PROJECT
        axios.post(`http://127.0.0.1:8000/api/v1/projectUpdate` , {
          'id' : project_id ,
          'projectName' : formValues.projectName ,
          'constructionType' : formValues.constructionType ,
          'addresse' : formValues.addresse ,
          'description' : formValues.description ,
          'image_url' : formValues.image_url
        }).then ( result => {

          console.log(result.data.project)
          const temp = result.data.project;
          useDispatch(addProject(temp))
             
        }
        ).catch(error => {
          console.log(error)
        } )
      
      }

You haven't provided a TS type for the action argument in either case reducer. So, by default, RTK's TS types assume that the generated action creator takes no arguments.

You need to do something like (state, action: PayloadAction<SomeTypeHere>) instead:
