v3 function schemas don't show error for missing fields on returns

Given code:

The function returns additional fields that are not on the returns schema. The expected behavior is that TS would throw an error due to key2 being an additional field on the type. Adding strict() does not fix this either

Yep either one is good.

Note that if TestSchema contains transforms you’ll want to use z.input instead of z.infer.

Ah interesting. I was thinking of this:

export const func = z
  .function()
  .args(z.string())
  .returns(TestSchema)
  .implement((arg1): z.infer<typeof TestSchema> => {
    // write code
  })
