Hello, I am new in ChIP-seq analysis. I tried to use ChIPQC make a quality control of my samples but something went wrong.

library(ChIPQC)
library(BiocParallel)
setwd("/mnt/data/home/tycloud/CUT_TAG")
samples=read.csv("GW_S3_SampleSheet.csv")
inputExp <- ChIPQC(samples,annotation = "hg19",chromosomes=1)

When I chose one chromosome to investigate, everything went well. However, when the number of chromosomes increased, some error appeared (only in BiocParallel ).

inputExp <- ChIPQC(samples,annotation = "hg19",chromosomes=c(1,2))

##Error: BiocParallel errors
##0 remote errors, element index: 
##8 unevaluated and other errors
##first remote error:

I have tried method like adding "BPPARAM <- SerialParam()", but it didn't work.

BPPARAM <- SerialParam()
inputExp <- ChIPQC(samples,annotation = "hg19",chromosomes=c(1,2),BPPARAM = BPPARAM)

What do unevaluated errors exactly stand for? and How to fix them? Thank you all in advance for your help!
