The Jacobian matrix evaluated at the steady state

Dear community
After running my .mod file, Dynare indicates that there is a problem.

Error using print_info (line 32)
The Jacobian matrix evaluated at the steady state contains elements that are not real or are infinite.

Error in check (line 48)
print_info(info, 0, options);

Error in expss.driver (line 387)
oo_.dr.eigval = check(M_,options_,oo_);

Error in dynare (line 293)
evalin(‘base’,[fname ‘.driver’]) ;

I need your expertise to solve this problem.
I would be very grateful if someone help me in any way.

Have a great day

Check your computations of the model-local variables. Yss is negative.
