Error message

I am getting the following error:

Error in 2:ncol(all_scores): argument of length 0

I am using the following script:

combine_PRS(
  pheno_file = "~/path/phenotype.txt",
  covariate_file = "~/path/covariate.txt",
  score_files_list = c("~/path/score_file1.sscore"),
  trait_specific_score_file = "~/path/cad_list.txt",
  pheno_name = "GDM",
  isbinary = TRUE,
  out = "GDM_combined_PRS",
  liabilityR2 = TRUE,
  IID_pheno = "IID",
  covar_list = c("parity", "bmi", "PC1", "PC2", "PC3", "PC4"),
  cat_covar_list = c("parity"),
  ncores = 4,
  is_extract_adjSNPeff = FALSE
)

I am using scores that I previously created using plink2.
scorefile.txt is formatted as

(IID FID PGS1 PGS2... etc)

Many thanks
