Error: Error using dynare (line 282) Dynare: preprocessing failed

hi everyone
I downloaded this DSGE code from the Github site and wanted to see the results by running it. But I got this error:

Error using dynare (line 282)
Dynare: preprocessing failed

What is the solution to the error?
Thank you in advance for your help
