}Common errors
- Vectors have different lengths.Nerdamer throws.
- A required field is missing or has the wrong type.Zod validation error, e.g. `Required` or `Expected string, received number`.
- Nerdamer cannot parse the expression (unbalanced parens, unknown function, stray characters).`Unexpected token …` or `… is not a valid expression`.
