Unable to collect the trace, got the error "One or more errors occurred. (Could not find a part of the path"

Hi
Just the tool I was looking for, I was planning to write myself specifically to get the thread stack .
I cloned you repo & built locally , I am getting following error when I ran with .net core 3 app.

DotNetEventPipe.exe collect -p 8924 -d 60 -f demo
Process ID : 8924
Duration   : 60
Trace file : E:\dev\dotnetapps\EventPipe-Diagnostics\DotNetEventPipe\bin\Debug\netcoreapp3.1\traces\demo.nettrace
[Trace started...]
One or more errors occurred. (Could not find a part of the path 'E:\dev\dotnetapps\EventPipe-Diagnostics\DotNetEventPipe\bin\Debug\netcoreapp3.1\traces\demo.nettrace'.)

If i give path for the trace file it works , DotNetEventPipe.exe collect -p 8924 -d 60 -f c:\dev\demo, but documentation says without path

Usage:
  DotNetEventPipe collect [options]

Options:
  -p, --processId <pid> (REQUIRED)    The process id to collect the trace for.
  -d, --duration <duration>           Duration in seconds to run the trace.
  -f, --traceFilename <filename>      Trace file name **(without path).**
  -?, -h, --help                      Show help and usage information

Default tracefile name is 33216-20200712144534.nettrace
processId + "-" + DateTime.Now.ToString("yyyyMMddHHmmss") + ".nettrace"

Default duration is 10 seconds.

Updated in the command line help as well.
