Blanchard Kahn Condition Error: Indeterminacy

Hi, I am trying to replicate Eggertsson et al. (2019). However, I am getting Blanchard Kahn condition error. Since the the problem is indeterminacy, I am assuming the error is due to the timing but I am not sure which timing of the variable to fix to run the .mod file. If I can get any help, I would really appreciate it. I have attached the .mod file. If anyone is looking at the .mod file, I have placed approximate solutions for Y and l because it’s really difficult to get analytical solutions for Y and l. Below are the expressions for Y and l.

Expression for Y:


Expression for l:

Below are the Blanchard Kahn condition error and Equilibrium conditions along with equations. Since there are 21 equations and 22 unknowns (I think the authors forgot to include the natural rate of interest r^{n}_{t} as one their endogenous variables), I have decided to make the natural rate of interest to be a constant (that is, r^{n}_{t} = r^{n}):

I may be wrong but I do not believe there are any predetermined variables in this model. Would it be possible to please notify me of any suspected predetermined variables from this model? Thank you in advance…

Anything that requires an initial condition is a state. So there are two of those, but they already have the correct timing in the screenshot.
