I could not get data from selectizeInput to esquisseUI


Your code is not a reprex, so I'm not sure what the issue might be, but one guess is that calling rawdata needs to be done with parentheses because it's a reactive variable:

 esquisse_res <- callModule(
      module = esquisserServer,
      id = "esquisse",
      data = rawdata()

If this does not help, please create a Shiny Reprex using this guide:
