Objects created by the .parse method, do not have the toString method

[caeus]

const someSchema = FT.Record({...})

const parsedObject = someSchema.parse(...)

console.log(parsedObject.toString) // prints undefined

That's quite the unexpected behavior!

We generate objects with null as the prototype using Object.create(null) to prevent potential security vulnerabilities with prototype pollution. The lack of .toString is a side effect of this. I don' think it's a major issue given that the output of .toString would not be very useful anyway.
