Issues with better-auth component

// Create Better Auth instance with organization plugin for multi-tenancy
export const createAuth = (
  ctx: GenericCtx<DataModel>,
  { optionsOnly } = { optionsOnly: false },
) => {
  return betterAuth({
    // Disable logging when createAuth is called just to generate options
    logger: {
      disabled: optionsOnly,
    },
    baseURL: siteUrl,
    database: authComponent.adapter(ctx),

    // Email/password authentication (non-verified for now)
    emailAndPassword: {
      enabled: true,
      requireEmailVerification: false,
      // Optional: add password requirements
      minPasswordLength: 8,
    },

    // User table configuration
    user: {
      // Additional user fields beyond Better Auth defaults
      additionalFields: {
        // Platform-level role - stored in userProfiles instead
        // Don't add custom fields here as they cause validation errors
        // Use triggers to sync to userProfiles table
      },
    },
