I would guess that the underlying reason is a difference in package 

I'd also guess that the problem is at 
https://github.com/vivekbhr/icetea/blob/master/R/detect_diffTSS.R#L125 , 
where summarizeOverlaps hands off the BPPARAM to ResizeReads via ..., 
which is then passed to GenomicRanges::resize where the function is not 
expecting an argument named BPPARAM. Probably simply replace l 131 with

   GenomicRanges::resize(reads, width = width, fix=fix)

Remember that your new package will be added to the 'devel' version of 
Bioconductor, so you should be building and testing on R-3.5 /  Bioc 3.7.

There seem to be several calls to bplapply in your code; it might pay to 
start the parallel back-end at the top of your function, as mentioned in
