assay %in% SeuratObject：：Assays（x） is not TRUE

[628511miao]

I am performing SPOTlight and I am getting this error:

res <- SPOTlight(

• x = sce1,
• y = stRNA,
• groups = sce$t_group,
• mgs = mgs_df,
• hvg = hvg,
• weight_id = "mean.AUC",
• group_id = "cluster",
• gene_id = "gene") Error in .extract_counts(y, assay, slot) : assay %in% SeuratObject::Assays(x) is not TRUE

This is the software version, data structure, running code and error message. What is the cause? How to solve it? Thank you very much!
