wpResponse.data is empty

[menuology-chris]

Hi-
Trying to implement this on an app I'm building but even with a WordpressSuccessResponse() the data varaible is empty in wpResponse.data

`
void fetchArticles() async {
final baseUrl = Uri.parse('https://mydomain.com/wp-json/wp/v2');
final client = WordpressClient(
baseUrl: baseUrl,
bootstrapper: (bootstrapper) => bootstrapper
.withStatisticDelegate((baseUrl, requestCount) {
//print('$baseUrl -> $requestCount');
})
.withDebugMode(true)
.build(),
);
client.initialize();

final request = ListPostRequest(
  page: 1,
  perPage: 1,
  order: Order.asc,
);

final wpResponse = await client.posts.list(request);
switch (wpResponse) {
  case WordpressSuccessResponse():
    final data = wpResponse.data; // List<Post>
    break;
  case WordpressFailureResponse():
    final error = wpResponse.error; // WordpressError
    break;
}

setState(() {});

}
`

With debug enabled, I can see the successful connection and even the WP data in the Response Text field of the response, but the wpResponse.data field remains empty.

Logs:

Is this a bug or am I just implementing it incorrectly? Thanks for your help!

Oh, this is on 8.0.7

wordpress_client: ^8.0.7

Hey @menuology-chris
I attempted to replicate the scenario you described and obtained the expected results. I used the same domain as the one in the log file you provided.

I suspect that the issue stems from your codebase. Since you are calling setState immediately after the network call, could you please verify your program flow? That might be causing the problem.

final baseUrl = Uri.parse('https://{ommited}.com/wp-json/wp/v2');

  // Simple Usage
  final client = WordpressClient(
    baseUrl: baseUrl,
  );

  client.initialize();

  final response = await client.posts.list(
    ListPostRequest(
      perPage: 1,
      order: Order.asc,
    ),
  );

  response.map<void>(
    onSuccess: (response) {
      print('Posts Count: ${response.data.length}');
      // prints Posts Count: 1, as expected
    },
    onFailure: (response) {
      print(response.error.toString());
    },
  );

Thanks for the quick reply.

So interestingly, all I did was switch out the response code from the Dart style to the WP style as you referenced

final wpResponse = await client.posts.list(request);
switch (wpResponse) {
  case WordpressSuccessResponse():
    final data = wpResponse.data; // List<Post>
    break;
  case WordpressFailureResponse():
    final error = wpResponse.error; // WordpressError
    break;
}

to

response.map<void>(
    onSuccess: (response) {
      print('Posts Count: ${response.data.length}');
    },
    onFailure: (response) {
      print(response.error.toString());
    },
  );

And now it works

void fetchArticles() async {
    final baseUrl = Uri.parse('https://{mydomain}.com/wp-json/wp/v2');

    final client = WordpressClient(
      baseUrl: baseUrl,
    );

    client.initialize();

    final response = await client.posts.list(
      ListPostRequest(
        perPage: 20,
        order: Order.asc,
      ),
    );

    response.map<void>(
      onSuccess: (response) {
        print(response.data);
      },
      onFailure: (response) {
        print(response.error.toString());
      },
    );

    setState(() {});
  }

Could there be something different with the Dart 3 style that would cause it to be missing the data?

@menuology-chris I had tried both methods before sharing the previous update and it was working for me. I have also retried with the same sample and it was still working on both approaches. There are no differences between the two approach. Could you please check again?
