having an issue in "normalized_height"

[taeyoonlee87]

I used the "nomalized_height" command and encountered the same error when it was running using a high-performance computing system (HPC).

In the previous works, this code worked without any issue though when it was running in my desktop and a high-performance computing system.

However, whenever I run it using HPC it gave me same error.

The error was indicated like

opt_output_files(las_cat) <-"/scratch/tl96575/tin0628/dtm/norm{XLEFT}_{YBOTTOM}" lasnorm <- normalize_height(las_cat, DTM) Chunk 14 of 635 (0.2%): state ✗ An error occurred when processing the chunk 14. Try to load this chunk with: chunk <- readRDS("/tmp/RtmpJhamdq/chunk14.rds") las <- readLAS(chunk) i is invalid type (matrix). Perhaps in future a 2 column matrix could return a list of elements of DT (in the spirit of A[B] in FAQ 2.14). Please report to data.table issue tracker if you'd like this, or add your comments to FR #657. Error in any_list[[1]] : subscript out of bounds Calls: normalize_height ... normalize_height.LAScatalog -> catalog_map -> catalog_apply -> engine_merge In addition: Warning messages: 1: There are 3755 points flagged 'withheld'. 2: In raster_cell_from_xy(raster, x, y) : NAs introduced by coercion to integer range Execution halted

Do you have ever seen this error?

Not at all. I need a reproducible exemple.
