Plumber + Future + Python

[fiorepalombina]

Dear Community,
I am building a plumber api that I use in some future sections.

In one of these sections I use functions that are written in python and every time I insert this python function inside a future::future({}) it crashes the process and gives me this output

DEBUG: END OF TROUBLESHOOTING GUIDE

as also reported in this PLumber + Future + Fastsam.

so my question is:
Can I use future with a function written in python?

Moreover now i have added to the future section all the necessary part to execute the code

 reticulate::use_python("C:/Program Files/Python310")
      
      source("functions_new.R")
      
      reticulate::source_python('predict_sam.py')
      reticulate::source_python('sentinel_elab.py')
      
      library(tidyverse)
      library(plumber)
      library(reticulate)
      library(jsonlite)
      library(DBI)
      library(sp)
      library(readxl)
      library(rgeos)
      library(raster)
      library(RPostgreSQL)
      library(sf)
      library(rpostgis)
      library(Rook)
      library(rgdal)
      library(rapidoc)
      library(NbClust)
      library(future)
      library(planetR)
      library(data.table)
      library(nasapower)
      library(owmr)
      library(gptstudio)
      library(RPostgres)
      library(httr)
      library(lubridate)
      library(promises)
      library(sen2r)
      library(shinyjs)
      library(emayili)
      library(geojsonsf)
      library(SPEI)
      library(RColorBrewer)
      library(mapview)
      library(echarts4r)
      library(base64enc)
      library(reshape2)
      library(soilDB)

and now i am getting this

<Rcpp::exception in eval(expr, p): KeyError: 1
>
