I continually encounter the error

Undefined variable “oo\_” or class  
"oo\_.exo\_steady\_state".

What does it mean exactly ? What is the problem with the steady state ? Thanks

This is a bug. Currently, you cannot use the steady state operator on exogenous variables. Replace

```auto

```

by its steady state 1.
