Additional Fields Not Working

@Better Auth I have set up additional fields in my better auth config

 user: {
    changeEmail: { enabled: true },
    deleteUser: { enabled: true },
    additionalFields: {
      role: {
        type: "string",
        required: false,
        defaultValue: "user",
        input: false,
      },
      about: {
        type: "string",
        required: false,
        defaultValue: "Sharing ideas and learning from the community.",
        input: false,
      },
    },
  },

 user: {
    changeEmail: { enabled: true },
    deleteUser: { enabled: true },
    additionalFields: {
      role: {
        type: "string",
        required: false,
        defaultValue: "user",
        input: false,
      },
      about: {
        type: "string",
        required: false,
        defaultValue: "Sharing ideas and learning from the community.",
        input: false,
      },
    },
  },

 user: {
    changeEmail: { enabled: true },
    deleteUser: { enabled: true },
    additionalFields: {
      role: {
        type: "string",
        required: false,
        defaultValue: "user",
        input: false,
      },
      about: {
        type: "string",
        required: false,
        defaultValue: "Sharing ideas and learning from the community.",
        input: false,
      },
    },
  },

 user: {
    changeEmail: { enabled: true },
    deleteUser: { enabled: true },
    additionalFields: {
      role: {
        type: "string",
        required: false,
        defaultValue: "user",
        input: false,
      },
      about: {
        type: "string",
        required: false,
        defaultValue: "Sharing ideas and learning from the community.",
        input: false,
      },
    },
  },

when i try to call updateUser

const { error } = await updateUser({
        name: value.name,
        about: value.about,
      });

const { error } = await updateUser({
        name: value.name,
        about: value.about,
      });

const { error } = await updateUser({
        name: value.name,
        about: value.about,
      });

const { error } = await updateUser({
        name: value.name,
        about: value.about,
      });

i get this error included in screenshot, but other plugins are registering well such as the username plugin, and i can set

username

username

username

username and

displayUsername

displayUsername

displayUsername

displayUsername, so am not sure whats actually going on
