Error when adding end_id to ti_slingshot

[ccruizm]

Good day,

When using ti_slingshot, I can give start_id and it runs with no issue but once I add end_id, I get the next error:

Output with start_id:

Traceback:

1. dynwrap::infer_trajectory(monocytes.pseudotime, dynmethods::ti_slingshot(shrink = 1L, 
 .     reweight = TRUE, reassign = TRUE, thresh = 0.001, maxit = 10L,

 .         "end_id"))
2. stop("Error during trajectory inference, see output above ↑↑↑", 
 .     call. = FALSE)

What would be the reason for this error?

Thanks in advance
