path: ReadonlyArray<string | number> | undefined

An array describing the JSON-path into the execution response which corresponds to this error. Only included for errors during execution.

readonly
positions: ReadonlyArray<number> | undefined

An array of character offsets within the source GraphQL document which correspond to this error.
