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

• I go to https://wikifunctions.beta.wmflabs.org/w/index.php?title=Special:CreateZObject&zid=Z14&Z14K1=Z10531 to create a new implementation
• I am trying to implement "is one" https://wikifunctions.beta.wmflabs.org/wiki/Z10531, a function that returns true if the input is 1 and false otherwise
• I click on code, and select JavaScript as the programming language
• I enter the following implementation:

function Z10531( Z10531K1 ) {
return Z10531K1.Z10015K1 === "1";
}

• I click "Publish"

What happens?:
Nothing

What should have happened instead?:
It should publish the implementation
