[Bug] Missing session_id causing quarantine rows

Module

Tracker

Describe the Bug

When using the tracking-script, quite a lot of rows end up in quarantine because they are missing a session_id. So far i have 340 correct rows and 150 in quarantine, so almost 1/3 of rows cannot be ingested.

Expected Behavior

I would expect session_id to have a fallback value, so that rows can be ingested properly.

To Reproduce

1. Add script to header in next.js app

<script
          defer
          src="https://unpkg.com/@tinybirdco/flock.js"
          data-host="https://api.tinybird.co"
          data-token={process.env.NEXT_PUBLIC_TINYBIRD_TOKEN}
        />

2. Rows end up in quarantine with error message ['Strict type checking failed. Object does not have column \'session_id\', you should send a value or recreate the table with a Nullable column type. While accessing jsonpath \'$.session_id\'']

Details

No response
