How to use same rejected in same slice in redux toolkit

I have this extrareducers:

extraReducers: builder => {
    builder.addCase(getTopicsByDcResponsable.fulfilled, (state, action) => {
      if(action.payload.status === 200){        
        state.error = '';
        state.userTopics.responsableTopics.push(...action.payload.data); 
      } else {
        state.error = action.payload.data;

      }    
    });

    builder.addCase(getTopicsByDcResponsable.rejected, (state, action) => {     
      state.error = action.payload;
    });
         
    builder.addCase(getTopicsbyDcentroEdit.fulfilled, (state, action) => {     
        if(action.payload.status === 200){
          state.error = '';
          state.userTopics.editorTopics.push(...action.payload.data);  
        } else {
          state.error = action.payload.data;
        }   
      });

    builder.addCase(getTopicsbyDcentroEdit.rejected, (state, action) => {     
      state.error = action.payload;
    });
  },

All the rejected recieve the same message in case that the backend has an error 'Network Error'.

In redux you can use the same reducer for all the errors.
How can i use the same rejected in redux Toolkit if all recieve the same error?
Thanks

You can define a single error handler function and pass it to the builder.addMatcher method.

Something like this should prevent redundancy.

const handleRejected = (state, action) => {
state.error = action.error.message === "Network Error" ? "Network Error" : "Unexpected Error";
};
extraReducers: builder => {
builder
.addCase(getTopicsByDcResponsable.fulfilled, (state, action) => {
if (action.payload.status === 200) {
state.error = '';
state.userTopics.responsableTopics.push(...action.payload.data); 
} else {
state.error = action.payload.data;
}    
})
.addMatcher(
action => action.type.endsWith("/rejected"),
handleRejected
)
.addCase(getTopicsbyDcentroEdit.fulfilled, (state, action) => {
if (action.payload.status === 200) {
state.error = '';
state.userTopics.editorTopics.push(...action.payload.data);  
} else {
state.error = action.payload.data;
}   
})
.addMatcher(
action => action.type.endsWith("/rejected"),
handleRejected
);
},

Edit: You can try this if you want to remove additional .addMatcher

const isRejected = action => action.type.endsWith("/rejected");
builder
.addCase(getTopicsByDcResponsable.fulfilled, (state, action) => {
// Handle fulfilled action for getTopicsByDcResponsable
})
.addCase(getTopicsbyDcentroEdit.fulfilled, (state, action) => {
// Handle fulfilled action for getTopicsbyDcentroEdit
})
.addMatcher(isRejected, (state, action) => {
// Handle all rejected actions
state.error = action.error.message === "Network Error" ? "Network Error" : "Unexpected Error";
});
