Integrated Cytotalk method error: non-numeric argument to numeric function

[AltayYuzeir]

Hello, I have been working with this Seurat data file, included in the link, it is not very big - https://uni-bonn.sciebo.de/f/1980218563. I have run it through the liana_wrap() function, and all integrated methods (natmi, sca, cellphonedb, logfc, connectome) work, but when I run it with the integrated cellchat method, I get an error, which I cannot understand.
