cant save logfile in pyomo

[MohammadSaeed Omidi]

im using gams 24.1 to solve mip model after solving when i want to save log file i got error 
here is my code

results = opt.solve(

            instance,

            tee=True,

            keepfiles=True,  # Keep intermediate files created by GAMS

            # logfile="gams_log.log",  # Log file for GAMS output

            report_timing=True

            # add_options=[

            #     'option reslim=36000;',

            #     # f'option save=gams_{version}.lst;'  # Save the list file

            # ]

            )

 after adding logfile="gams_log.log",  # Log file for GAMS output i got error below
gams: **** Error: Parameter error(s)
