error when running celltree_maptpx

[ch8316f5eyu]

Hi, when I run the method of "celltree_maptpx", there is an error that indicates no expression associated with dataset. But I already add it by wrap_expression but is OK for other methods. How to solve it?

Dataset <- wrap_expression(counts = GetAssayData(seurat, 'count') %>% t, expression = GetAssayData(seruat, 'data') %>% t)  
model <- infer_trajectory(Dataset, 'celltree_maptpx')

The error message is:

Error in get_expression(dataset, expression_source) :
  No expression found in trajectory, please provide the expression through the expression_source argument. This can be an expression or counts matrix, or a dataset containing the expression.

And it didn't work even I add "parameters = list('expression_source' = get_expression(Dataset, 'counts')" inside the function infer_trajectory
