getting error when running gsea

[ChenyuZhang97]

Hi, I am trying to run the code pasted below, and get this error:

LR_List <- liana::select_resource('CellChatDB')[[1]] %>%
            select(ligand = source_genesymbol,
                   receptor = target_genesymbol) %>%
            unite('interaction',
                  ligand,
                  receptor,
                  sep = '^') %>%
            pull(interaction)
          
          LR_Set <- c2c$external$generate_lr_geneset(lr_list = LR_List,

                                                     pathwaydb = 'GOBP', #GOBP, KEGG,  Reactome
                                                     readable_name = TRUE)
         
          LR_Loadings <- factors[['interactions']] %>%

And by running this command reticulate::py_last_error(), I got:

I'm able to run the Liana x tensor-cell2cell R tutorials up to this point. Any suggestion for this? Thanks!
