Dear Professor,
I tried to run CytoTalk with my data , but with an error message "Error in startsWith(names(x), "node") : non-character object(s)".

results <- CytoTalk::run_cytotalk(lst_scrna, type_a, type_b, cutoff_a = .1, cutoff_b = .1, beta_max = 100)

I met the same error. After I normalized the counts data, the algorithm has run smoothly
