Assume this code, somewhere in a module or in a tpl file:

$node_wrapper = entity_metadata_wrapper('node', node_load($nid));
echo $node_wrapper->property_that_does_not_exists->value();

We all get the error page (blocking everything else from execution) with message:

EntityMetadataWrapperException: Unknown data property property_that_does_not_exists. in EntityStructureWrapper->getPropertyInfo() (linea 349 di /var/www/vhosts/comelovuoitu.it/httpdocs/sites/all/modules/entity/includes/entity.wrapper.inc).

But we dont get any info about the file/function that raised the error asking for "property_that_does_not_exists".

I edited the getPropertyInfo() method in EntityStructureWrapper class to look like:

  public function getPropertyInfo($name = NULL) {
    $this->spotInfo();
    if (!isset($name)) {
      return $this->propertyInfo['properties'];
    }
    if (!isset($this->propertyInfo['properties'][$name])) {
      
      $db = debug_backtrace(true, 3);
      if(isset($db[2]))
      {
        $msg = '(' . $db[2]['file'] . ' on line ' . $db[2]['line'] . ')';
      }
      else
      {
        $msg = '';
      }
      throw new EntityMetadataWrapperException('Unknown data property ' . check_plain($name) . '.' . $msg);
    }
    return $this->propertyInfo['properties'][$name] + $this->info['property defaults'] + $this->propertyInfoDefaults;
  }

So i get the file and the line where the unknown property has been invoked.

I get the exact same problem and I was wondering how to properly locate and apply this fix to which exact class, module or file.

EntityMetadataWrapperException: Unknown data property field_published. in EntityStructureWrapper->getPropertyInfo() (line 339 of /home/mysite/public_html/sites/all/modules/entity/includes/entity.wrapper.inc).

AFAIK the only way to do that _cleanly_ is to use debug_backtrace() (as in my first post) to dig backwards in the exception invocation.

You can to that inside the EntityMetadataWrapperException (about line 1107 of sites/all/modules/entity/includes/entity.wrapper.inc)

EntityMetadataWrapperException: Invalid data value given. Be sure it matches the required data type and format. in EntityMetadataWrapper->set() (regel 122 van /var/www/vhosts/xxx/httpdocs/profiles/commerce_kickstart/modules/contrib/entity/includes/entity.wrapper.inc).

It after filtering on a product brand ( 46 items in it )

Brand has cross variation types

Line 118 - 128

* Set a new data value.
*/
public function set($value) {
if (!$this->validate($value)) {
throw new EntityMetadataWrapperException('Invalid data value given. Be sure it matches the required data type and format.');
}
$this->clear();
$this->data = $value;
$this->updateParent($value);
return $this;
}

Edit
I found my issue
It has to do with disabled products in the filtered entity
