Steps to replicate the issue (include links if applicable):

• currently, if you go to https://www.wikifunctions.org/view/en/Z16680

What happens?:

• the first implementation (for Z16681) is marked as failed
• with the following response:

Error type: Invalid executor response
Expected result: Z16661
Actual result: { "Z1K1": "Z5", "Z5K1": "Z564", "Z5K2": { "Z1K1": { "Z1K1": "Z7", "Z7K1": "Z885", "Z885K1": "Z564" }, "Z564K1": "" } }

What should have happened instead?:
This test probably should pass.

There shouldn't be an empty Z564K1 (Executor response), so why is there one?
