The type 'Object' does not have an index signature that accepts parameters of type 'string'

**I need assistance with solving this problem. I am encountering an error message and would appreciate some help. The error states: Element implicitly has an 'any' type because expression of type 'string' can't be used to index type 'Object'.**

import { Injectable } from '@angular/core';
import {HttpClient} from '@angular/common/http';
import {map} from 'rxjs/operators';
import { IProperty } from '../property/IProperty.interface';
import { Observable } from 'rxjs';

@Injectable({
 providedIn: 'root'
})

export class HousingService {

 constructor(private http: HttpClient) { }

getAllProperties(): Observable<IProperty[]>{
return this.http.get('data/properties.json').pipe(
  map(data => {
    const propertiesArray: Array<IProperty> = [];
    for (const id in data){
      if(data.hasOwnProperty(id)) {
        propertiesArray.push(data[id]);
      }
    }
    return propertiesArray;
  })
);
}
}

Answer №1

Based on the code you provided, it seems like you are fetching all values from properties in JSON format. The reason for the error is that the data type is currently set as empty {}, because you haven't specified it in the generic get<T = {}>() method.

You can make a small adjustment to the code like this:

getAllProperties(): Observable<IProperty[]>{
  return this.http.get<Record<string, IProperty>>('data/properties.json').pipe(
    map(data => Object.values(data));
  };
}

Once you make these changes, everything should work smoothly.
