Command error (undefined): Cannot read properties of undefined (reading 'startTokenId')

[botnumberseven]

After upgrade to v8.1.1+hotfix.9 I can see a fair amount of these (one every couple of minutes)
ERROR: Command error (undefined): Cannot read properties of undefined (reading 'startTokenId').
Would be nice to add command name into this error message, so it's clear what command failed.

Typical context looks like this:

It seems someone is sending broken requests and the node can't process them, node failes to handle them, it should fail more gracefully.

We will fix it. Thanks!
