SOE - DSGE Model - Singular Matrix

I’m with this error below, could someone help me to audit and solve?

Warning: Matrix is singular to working precision.

In evaluate_steady_state (line 263)
In steady_ (line 55)
In steady (line 81)
In Lista_3_Eduardo_Marinho (line 380)
In dynare (line 223)Lista_3_Eduardo_Marinho.mod (5.8 KB)

Are you sure your model has a unique steady state that Dynare could find? Usually in New Keynesian models the price level is not stationary. Only inflation rates and relative prices are uniquely defined.

I found the error, a parenthesis in one equation. Thanks for trying help me.
