TypeError: The "original" argument must be of type Function

[OPerel]

Hello,
I'm trying to use the package in a React (TypeScript) app but I get the error in the title every time.
Here's how I use it:

public updateStoreOwnerProfile = async (_id: string, newStore: StoreOwner): Promise<void> => {
    try {
      await writeJsonFile('./collections/storeOwners.json', newStore);
    } catch (err) {
      console.log('Error writing to file: ', err)
    }
  }

This is the error I get:

Error writing to file:  TypeError: The "original" argument must be of type Function

The second argument being passed is a plain TS object:

{
  address: "bla bla bla",
  createdAt: "00/00/0000",
  isSigned: true,
  notifications: true,
  shopDescription: "bla bla bla",
  storeName: "bla bla",
  user: "MEaFxRiwBAgX8JGGwZ7o2N7qKkp2",
  _id: "1234567890987654321"
}

The file already exits in the path specified and I'm trying to update it (I also tried writing to a new file and got the same error).

Thanks a lot!
