Correct types: src/shared/file-record-types.js

The TypeScript compiler requires that these methods conform to the API
signature even though they are considered "virtual" in a classical
object-oriented programming sense. Because the TypeScript compiler
considers returning nothing a violation ("A function whose declared type
is neither 'undefined', 'void', nor 'any' must return a value.") but is
satisfied by throwing an error, throw an error to indicate the virtual
status of these methods.
