Reactive context was created in one process and accessed from another

Dear Seqplots developers,

I am trying to use the Seqplots 1.12.0 R package. I am able to upload the bed and bw files but when I try to plot them I always get

Error in ctx$onInvalidate(function() { : Reactive context was created in one process and accessed from another

I think this is a shiny of javascript error, but I am unable to figure out by myself. may you help me?
