Undefined index: rdftype in schemaorg_ui_term_load()

Hi Scor, thank you for your quick response.. I uninstalled and installed the module and updated the new dev as you suggested.. Still I get the same error.. except that the line number has changed... I am using Schema cache module and that was run by using cron.

Notice: Undefined index: rdftype in schemaorg_ui_term_load() (line 205 of all/modules/schemaorg/modules/schemaorg_ui/schemaorg_ui.module).
Warning: Invalid argument supplied for foreach() in schemaorg_ui_term_load() (line 211 of /all/modules/schemaorg/modules/schemaorg_ui/schemaorg_ui.module).

Hi Scor, I noticed that I get the error only when I enable efb module. In fact variation types do not have an option to map the schema.org and when we open variation types edit field, it brings up an option to map the field with empty values. Is there a way we can map schema.org under variation types?

Do you suggest I come on IRC? The lines are:

204
if ($field == 'rdftype') {

198 -216

/**
* Loads the schema.org term for a particular Drupal field or rdftype.
*/
function schemaorg_ui_term_load($type, $bundle, $field) {
$terms = array();
$mapping = rdf_mapping_load($type, $bundle);
if ($field == 'rdftype') {
$terms = $mapping['rdftype'];
}
elseif (!empty($mapping[$field]['predicates'])) {
$terms = $mapping[$field]['predicates'];
}
// Return the first schema: term.
foreach ($terms as $term) {
if (strpos(trim($term), 'schema:') === 0) {
return str_replace('schema:', '', $term);
}
}
}

Yes, That has fixed the error.. Thank You Scor...

However, the mapping of the metadata fields has not been enabled for variation types.. Are we able to extend the mapping towards Variation types as well??? Thanks again...

Hi Scor, I have added 4 screenshots based on the sequence. In the content type (Display), I have an option to specify the shema and am able to map the fields based on the schema. However, when I create a variation, I do not have an option to map the schema and hence I am not able to choose the fields against the schema. I am using Entity Fields Builder module to have the fields mapped.
