Question

我正在使用gatsby wordpress插件从托管的WP网站检索我的帖子。在本地，gatsby构建工作正常，并且检索了我的所有ACF字段。但是，在我的Netlify部署上，属性本地文件似乎为空。使用其他字段，可以正确检索ACF字段。

这是我的GraphQL查询：

{
  allWordpressPost {
            edges {
              node {
                id
                wordpress_id
                date
                guid
                modified
                slug
                status
                type
                link
                title
                content  
                acf {
                  description
                  title
                  icon
                  link
                image{             
                    slug
                    title
                    localFile{
                     childImageSharp{
                      sizes{
                        sizes
                      }
                      resolutions{
                        srcSet
                        src
                      }
                    }
                    }
                    source_url
                    link
                  }

                }
              }
            }
          }
        }

我已经在此ticket所引用的Wordpress函数文件中实现了nullify函数修复程序：

function nullify_empty($value, $post_id, $field)
{
    if (empty($value)) {
        return null;
    }

    return $value;
}

add_filter('acf/format_value_for_api/type=text', 'nullify_empty', 100, 3);
add_filter('acf/format_value_for_api/type=image', 'nullify_empty', 100, 3);
add_filter('acf/format_value_for_api/type=repeater', 'nullify_empty', 100, 3);

我发现与本地日志相比，Netlify上的构建日志有何不同。我认为这是问题所在：

在本地，对于同一警告仅显示以下内容：

这是在Netlify构建日志中记录的ACF字段的示例。注意localfile属性：
