I apologize for the confusion. Upon reviewing my previous response, I realize that I made an error in providing a SPARQL query for fetching non-binary individuals from Wikidata. I apologize for any inconvenience caused. Here's the corrected SPARQL query:

```sparql
PREFIX wd: <http://www.wikidata.org/entity/>
PREFIX wdt: <http://www.wikidata.org/prop/direct/>
PREFIX wikibase: <http://wikiba.se/ontology#>
PREFIX rdfs: <http://www.w3.org/2000/01/rdf-schema#>

SELECT DISTINCT ?person ?personLabel WHERE {
  ?person wdt:P21 wd:Q48270;    # Gender: non-binary
          rdfs:label ?personLabel.
  FILTER(LANG(?personLabel) = "en").
}
LIMIT 50
```

In this corrected query, the gender property has been updated to `wdt:P21` with the value `Q48270` representing non-binary individuals.

Please note that the availability and accuracy of data in Wikidata can vary, and it's possible that the results may not be exhaustive or fully up to date.
