我认为问题出在这行(我认为是#140(：
$editor = wp_get_image_editor($file);
根据文档，如果出现任何问题，wp_get_image_editor()将返回WP_Error。
因此，您可以尝试添加一个条件来检查返回的$editor是否为WP_Error。如果没有，请调整大小(因为如果成功，将返回WP_Image_Editor的实例(。
例如：
$editor = wp_get_image_editor($file);
if( ! is_wp_error( $editor ) ) {
$editor->resize($width,$height,$crop);
$dest_file = $editor->generate_filename();
$editor->save($dest_file);
return $dest_file;
}
else
{
return $file;
}
