Error vapply(df, class, FUN.VALUE = NA_character_) : values must be length 1, but FUN(X[[1]]) result is length 3 (when running a LCA in R)

I am using Mplusautomation to run a LCA with a distal outcome in R. Both the indicators and the distal are ordinal variables, with scales ranging from 1 to 5 for the indicator variables and 1 to 4 for the distal variables.

  TITLE = "BCH lca with distal outcome;", 
  
  DATA = "LISTWISE=ON;",
  
  VARIABLE = 
    "usevar = int_3 sw_3 soc_3 alt_3 gov_3 for_3;
    auxiliary = claim_5 claim_6 (bch);
    classes = c(5);",
  
  ANALYSIS =
    "estimator = mlr;
    type = mixture;
    starts = 500 100;
    processors = 10;",
  
  OUTPUT = 
    "type = plot3;
    series = int_3 sw_3 soc_3 alt_3 gov_3 for_3(*);",
  
  usevariables = c("int_3", "sw_3", "soc_3", "alt_3", "gov_3", "for_3", "claim_5", "claim_6"),
  rdata =  data_lca_distal_Mpanel_220918)

m_bch_fit <- mplusModeler(m_bch,
                          dataout=here("paper 2"),
                          modelout=here("paper 2"),
                          check=TRUE, run = TRUE, hashfilename = FALSE)

However, when I run the code I get the following error message:

Error in vapply(df, class, FUN.VALUE = NA_character_) : values must be length 1, but FUN(X[[1]]) result is length 3

I am new to Mplus and R and have no idea what this error means. I extracted the indicators to a data frame without NA's, and to a data frame with NA = -99 (defining MISSING ARE ALL -99 in the code). However, that did not work and the error still appears. Does anyone know why this error appears and what I can do about it? I really appreciate any help on this matter.

Thank you!
