I am creating nodes programmatically. I Have written following code,

$e = entity_create('node', array('type' => 'some_node'));
// Specify the author.
$e->uid = 1;
// Create a Entity Wrapper of that new Entity.
$entity = entity_metadata_wrapper('node', $e);

// Specify the title.
$entity->title = 'Some Title';
$entity->body = 'abc';

On giving value to body i am getting following error. Commenting body it works fine

EntityMetadataWrapperException: Invalid data value given. Be sure it matches the required data type and format. in EntityMetadataWrapper->set()

What is causing this error and how can I fix it?

Body is a Field API field and not a native PHP variable, therefore you cannot assign values to it like that. Instead, you would need to pass an array with the following keys:

  'value' => 'This is the body',
  'summary' => 'This is the summary',
  'format' => 'full_html',

If you wish to set the value for a specific language, you call prior to set:

$entity->language(LANGUAGE_NONE); // or 'en' or whatever
