Help figuring out what part of my object is throwing the subscript out of bounds error

[JasperGattiker]

Hello again. When running the initial celltalk function, I encounter the following error: .subscript.2ary(x, i, j, drop = TRUE) : subscript out of bounds. I've included the traceback below. This error occurs whether the scaled/normalized RNA assay is structures as a V5 or V3/4 Seurat assay. Has anyone else encountered this, and what did you do to fix it? Looking at the traceback, I can't figure out what to start troubleshooting.

celltalk(input_object=Integrated_DF,
metadata_grouping="CellTypes_Assigned",
ligand_receptor_pairs=ramilowski_pairs,
number_cells_required=100,
min_expression=1000,
max_expression=20000,
scramble_times=10)

Error in .subscript.2ary(x, i, j, drop = TRUE) : subscript out of bounds
