Error while using a BED file

Hi,

I am a complete newbie in data science and R but I have been trying to use the script to analyze CNA for a targeted capture sequencing in cfDNA as following:

/scratch/scripts/runIchorCNA.R --id tumor_sample   --WIG test.wig --ploidy "c(2,3)" --normal "c(0.5,0.6,0.7,0.8,0.9)" --maxCN 5   
--gcWig /scratch/inst/extdata/gc_hg38_1000kb.wig   --mapWig /scratch/inst/extdata/map_hg38_1000kb.wig   
--centromere /scratch/inst/extdata/GRCh38.GCA_000001405.2_centromere_acen.txt   
--includeHOMD False --chrs "c(1:22, \"X\")" --chrTrain "c(1:22)"   --estimateNormal True --estimatePloidy True 
--es[AtimateScPrevalence True   --scStates "c(1,3)" --txnE 0.9999 --txnStrength 10000 --outDir ./ 
--exons.bed  CNV.target.bed --genomeBuild hg38

and I am keep getting the following error:

and when running without using a bed file it works but gives the following warnings:

1: In KernSmooth::bkde2D(x, bandwidth = bandwidth, gridsize = nbin,  :
  Binning grid too coarse for current (small) bandwidth: consider increasing 'gridsize'
2: In KernSmooth::bkde2D(x, bandwidth = bandwidth, gridsize = nbin,  :

4: In KernSmooth::bkde2D(x, bandwidth = bandwidth, gridsize = nbin,  :
  Binning grid too coarse for current (small) bandwidth: consider increasing 'gridsize'

my .BED file looks like this

Chr start   end

1   23559184    23559465

I'll appreciate your advice. Bests, Mouhamad
