I am using VSCode with the official vscode-lldb extension. When I try to
list the breakpoints in the debug console get the message:
```
br list
can't evaluate expressions when the process is running.
```
I know that this is wrong and you need to use
```
`br list
(lldb) br list
No breakpoints currently set.
```
but the error message is misleading. I cleaned up the code and now the
error message is
```
br list
sbframe object is not valid.
```
which is still not perfect, but at least it's not misleading.
