Description

On Wikifunctions.org, fetching P5137/item for this sense returns the error below. However, it works fine for other properties, such as instance of and demonym of.

Update (still on 28 February 2025): I've seen this error multiple times over the last few days. Just now, I ran it in the sandbox, and it completed successfully. Then I returned to the UI and ran it again and it completed successfully.

The input to the API (wikilambda_function_call_zobject) looks okay: {"Z1K1":"Z7","Z7K1":"Z6822","Z6822K1":{"Z1K1":"Z6092","Z6092K1":"P5137"}}
