Create better error messages for broken scripts

If you try a command that do not exist you get:

```
[2025-01-09 13:49:49] INFO: Mark run as failure with message: Cannot read properties of undefined (reading 'run')
[2025-01-09 13:49:49] ERROR: TypeError: Cannot read properties of undefined (reading 'run')
```

Maybe we could do something better here so we can actually see what is broken?
