How to fix Uncaught Error: Not authenticated?

When I reload the page within my app, I get this error message in the Convex logs within the dashboard:

Aug 17, 18:58:42

Q
users:getUser
failure
22ms
Uncaught Error: Not authenticated
    at handler (../convex/users.ts:50:4)

Aug 17, 18:58:42

Q
users:getUser
failure
22ms
Uncaught Error: Not authenticated
    at handler (../convex/users.ts:50:4)

This isthe getUser query:

export const getUser = query({
  handler: async (ctx) => {
    const identity = await ctx.auth.getUserIdentity()

    if (!identity) {
      throw new Error("Not authenticated")
    }

    const userId = identity.subject

    const user = ctx.db
      .query("users")
      .withIndex("by_user", (q) => q.eq("userId", userId))
      .first()

    return user
  },
})

export const getUser = query({
  handler: async (ctx) => {
    const identity = await ctx.auth.getUserIdentity()

    if (!identity) {
      throw new Error("Not authenticated")
    }

    const userId = identity.subject

    const user = ctx.db
      .query("users")
      .withIndex("by_user", (q) => q.eq("userId", userId))
      .first()

    return user
  },
})

The query does seem to work, as I am logged in to the app. Is there a loading step to add to the query, so the error doesn't show unless the identity is in fact missing?

Don't call the query until you know you're authenticated on the client side:

const Component = () => {
  // replace w/ Clerk equivalent if using Clerk
  const { isLoading, isAuthenticated } = useConvexAuth()
  const user = useQuery(api.user.getUser, isAuthenticated ? {} : 'skip')

  return <div>isAuthenticated: {isAuthenticated}</div>
}

const Component = () => {
  // replace w/ Clerk equivalent if using Clerk
  const { isLoading, isAuthenticated } = useConvexAuth()
  const user = useQuery(api.user.getUser, isAuthenticated ? {} : 'skip')

  return <div>isAuthenticated: {isAuthenticated}</div>
}
