Error: Failed to fetch the data from the Firebase database

I have recently added an edit button to my product list, but when I click on it, the form page opens with no data populated. Upon debugging in my product.service.ts file, I noticed that it outputs null when using console.log(p). I believe this is where the main issue lies.

[I am quite new to Angular, so any assistance would be greatly appreciated].

Here is a snippet of my product form template-

<div class ="row">
    <div class="col-md-6">
        <div class="card" style="width: 30rem;">
            <img [src]= "product.imageUrl" class="card-img-top" *ngIf= "product.imageUrl">
            <div class="card-body">
              <h5 class="card-title"> {{ product.title }}</h5>
              <p class="card-text"> {{ product.description }} </p>
            </div>
          </div>
    </div>

    <div class="col-md-6">
        <form #f="ngForm" (ngSubmit)="save(f.value)">
           [The rest of the form code goes here]
        </form>
    </div>
</div>


Product-form.component.ts

import { Component } from '@angular/core';
[Remaining imports and logic for Product Form component]
}

Lastly My product service implementation can be seen below- (product.service.ts) -

import { Injectable } from '@angular/core';
[Code for ProductService with create, getAll, and get methods]
}

Answer №1

After some investigation, I discovered the root of the issue. In my firebase products node, I noticed an additional space at the end that was causing the problem.

By fixing this error in my product.service.ts file, I successfully resolved the issue.

get(productId: string){
    return this.db.object('/products/' + productId);
}
