Error: Unable to iterate over data.data due to its type

I am attempting to fetch images from the woocommerce API and here is the code I am using:

this.config.getWithUrl(this.config.url + '/api/appsettings/get_all_banners/?insecure=cool')
.then((data: any) => {
this.banners = data.data;
     console.log(this.banners);
});

However, I encountered this error:

consolelogs.js:49 ERROR Error: Uncaught (in promise): TypeError: data.data is not iterable

Answer №1

In order to properly handle the data returned from the API, it is recommended to assign data.data to another variable after processing the original result. This can be achieved with the following code snippet:

this.config.getWithUrl(this.config.url + '/api/appsettings/get_all_banners/?insecure=cool')
.then((data: any) => {
     var original_data = JSON.parse(JSON.stringify(data));
     console.log(original_data);
this.banners = original_data.data;
     console.log(this.banners);
});

It is important to note that the data format may not always be correct, so there could potentially be issues with how the data is structured.
