Bug report

Describe the bug

When you verify an OTP, the session is not persisted to localStorage, auto-refresh is not started, and the user is undefined.

I believe this is because the return payload of verifyMobileOPT is:

 {
  "access_token": "...",
  "expires_in": ...,
  "refresh_token": "...",
  "token_type": "bearer"
}

Note that this is does not include expires_at and user.

If we then look at the definition of _saveSession we can see why:

  private _saveSession(session: Session) {
    this.currentSession = session
    this.currentUser = session.user

    const expiresAt = session.expires_at
    if (expiresAt) {
      const timeNow = Math.round(Date.now() / 1000)
      const expiresIn = expiresAt - timeNow
      const refreshDurationBeforeExpires = expiresIn > 60 ? 60 : 0.5
      this._startAutoRefreshToken((expiresIn - refreshDurationBeforeExpires) * 1000)
    }

    // Do we need any extra check before persist session
    // access_token or user ?
    if (this.persistSession && session.expires_at) {
      this._persistSession(this.currentSession)
    }
  }

A couple things here:

1. Because session.user is null currentUser is set to be null
2. Without expires_at the auto-refresh system is never started
3. Without expires_at, the session is not persisted

To Reproduce

1. Sign in via OTP
2. See that the response does not include expires_at and user is undefined
3. Refresh the page
4. Session is not persisted/recovered

Expected behavior

I expect the session signing in via verifyOTP to work the same as signing in via magic link & password

Additional context

I was able to work around this by

1. Verifying the OTP
2. Fetch the user via api.getUser
3. Calculate expires_at from current_time & expires_in
4. Create a new session based on the return of verifyOTP and steps 2 & 3
5. Manually call both _saveSession(newSession) and _notifyAllSubscribers('SIGNED_IN')

This is not ideal as it relies on calling "private" functions, but it gets everything to work

@jaredramirez thanks for providing these steps! Worked for me as well.

I'm guessing this issue is also related to https://github.com/supabase/gotrue/issues/141

Hey @jaredramirez and @dshukertjr, this issue should have been fixed sometime ago already! See here

Feel free to reopen this if it's still a problem!
