gistic : Error in file.info(file) : invalid filename argument

[HiraDatascience]

I am trying to run the following laml.plus.gistic command but getting this error.
laml.plus.gistic = read.maf(maf = MIBC_cleanmaf,

•                            gisticAllLesionsFile = "all_lesions.conf_99.txt",
  

•                            gisticAmpGenesFile = "amp_genes.conf_99.txt",
  

•                            gisticDelGenesFile = "del_genes.conf_99.txt",
  

•                            gisticScoresFile = "scores.gistic",
  

•                            isTCGA = TRUE,
  

•                            verbose = FALSE,
  

• )
  Error in file.info(file) : invalid filename argument
  

Note that my working directory is set to the folder of my PC that contains gistic result files.
