Summary

0050478: State compression on occasions breaks the state on deployed pos2

Description

If we refresh pos2 without any previous state and no data of the application, it breaks with the following error continuously appearing in the terminal:
TypeError: Cannot read properties of undefined (reading 'length')
at Object.checkMaximumNumberEventsPerMessage (POS2.js:16745:30)

If we take a look at the state after this happens, we encounter a state that is semi-compressed, and this seems to be the thing that's generating that error. It is not very clear what is causing it, for now we know is not the service workers, as this also happens on locally node deployed pos2.

Check the attached screenshot and video for more details.

Steps To Reproduce

1. Go to pos2 in livebuilds: https://livebuilds.openbravo.com/retail_pos2_pgsql/web/pos/?terminal=VBS-2 [^]
2. Open developer tools in chrome, and go to tab "Application"
3. Click on the left, click on Storage, and then on the button "Clear site data"

Refresh the web, you should reproduce the problem. Check the attached gif for extra info.
