Unable to update Zwave JS to MQTT from 0.6.2 to 0.7.0

When I click on the update button, it brings up the snapshot page and when I turn off the snapshot and click update the progress wheel goes round a couple of times and then disappears and the addon goes back to the info page with the update still showing.

If I look at my HA logs I see this error:

I have tried stopping the addon before running the upgrade but the issue still happens.

I am running HassOS 5.12, HA Core core-2012-3-4 and Supervisor supervisor-2021-3-6

Any ideas on what is going on?
