Cannot output any pseudo colours

Hello - my issue is the title: I'm unable to output any pseudocolour range in my pathview plots, they are all coloured the same green shade. I'm not sure if I don't have my pathview function set up correctly -- would appreciate any help! Thank you!

Here is the example code I am running & the output I get:

mypathway<-"vvi03060"
genes<-c("100241050","100243802","100244217","100244265","100247624","100247887","100248517","
100248990","100250268","100250385","100250458","100251379","100252350","100252527","100252725","
100252902","100253826","100254350","100254429","100254996","100255515","100256046","100256113","
100256412","100256941","100257568","100257730","100258179","100258854","100259285","100259443","
100260422","100260431","100261219","100262919","100263033","100264739","100265371","100266802","
100267343","100267692","100852861","100853033","100854110","100854416","100854647","100855182","
104879783","109122671")
logFC<-rnorm(length(genes),-0.5,1)
names(logFC)<-genes
pathview(gene.data=logFC,species="vvi",kegg.dir = paste0(pathPlots), pathway=mypathway)

Result is the same if I add limit = list(gene=c(-2,2), cpd=1) or limit = list(gene=1, cpd=1) as an argument.

vvi03060
