Dear EXCITING band

When trying to excitonic wavefunctions calculations on top of a BSE with exciting-carbon, I come across this error:

"Error in arraytointeger
Too many elements found"

I followed exactly from "Exciton Analysis and Visualization" tutorial section. However, when I did the original tutorial for LiF, everything was normal and I got the reference results. Does anybody have an idea about this error? The input file is also attached here. It should be noted that splitting execution into some sequential tasks, i.e. ground state, G0W0, and finally BSE calculation was not the solution. In addition, the BSE calculation was down solely without adding excitonic analysis elements!

Regards
