additionalFields need defaultValue even for non required field

Hey i have the error that there isn't defaultValue on my field but my fiel has to be not required, and i try to connect using google oauth, on my express app.

Can someone help me understand why it says it needs a defaultValue (and i try with or without the line defaultValue: "" but same issue) ?

thank you all 😉

here is my auth.ts file :

import { betterAuth } from "better-auth";
import { createPool } from "mysql2/promise";
import {
  openAPI,
  oAuthProxy,
  multiSession,
} from "better-auth/plugins";
import { nextCookies } from "better-auth/next-js";
import { passkey } from "better-auth/plugins/passkey";
import transporter from "./email/nodemailer";
import dotenv from "dotenv";

dotenv.config();

export const auth = betterAuth({
  appName: "EPF Projets - API Gateway",
  database: createPool({
    ...
  }),
  user: {
    additionalFields: {
      firstName: {
        type: "string"
      },
      sex: {
        type: "string",
        required: false,
        defaultValue: "",
      },
      phone: {
        type: "string",
        required: false,
        defaultValue: ""
      },
      address: {
        type: "string",
        required: false,
        defaultValue: ""
      },
      city: {
        type: "string",
        required: false,
        defaultValue: ""
      },
      zipCode: {
        type: "string",
        required: false,
        defaultValue: ""
      },
      country: {
        type: "string",
        required: false,
        defaultValue: ""
      },
      bio: {
        type: "string",
        required: false,
        defaultValue: ""
      }
    }
  },
  ...
}
