[BUG] Incorrect file path for graph otp_build_graph()

[CMKnott]

Describe the bug

I'm building an open trip planner (OTP) graph on Ubuntu using R.

I've specified my OTP folder with

path_data <- here::here("Input", "OTP")

And I get

[1] "/home/Projects/Transit Isochrone Map/Input/OTP"

But when I go to create the graph with this function

log1 <- opentripplanner::otp_build_graph(
  router = "Singapore",
  dir = path_data,
  otp = path_otp) 

I get this error

Warning: There are no osm.pbf files in /home/Projects/Transit Isochrone Map/Input/OTP//graphs//Singapore 
Error in opentripplanner::otp_build_graph(router = "Singapore", dir = path_data,  : 
Basic checks failed, please check your inputs

For some reason opentripplanner has added two forward slashes to the file path instead of one. Any idea why this has happened?

Expected behaviour
The graph should assemble based on the correct file

Additional context
Graph building works for the training folder of the Isle of Wight, but working on my own graphs doesn't seem to work.

The problem is the file name. It should be something.osm.pbf not just osm.pbf OTP checks for .osm.pbf files
