Getting errors using routing function in QGIS OSM Tools plugin

Question

I thought I found just the right tool for creating routes from all points in one layer to all points in another layer: The "Routing" function in OSM Tools. Unfortunately I am receiving errors trying to execute it.

I am getting the following messages: INFO: "Limit exceeded : Request limit of 40 per minute exceeded. Wait for 0.003889799118041992 seconds" like ten times.

Then there is the Python warning:

traceback:
warning:sys:1: ResourceWarning:
unclosed <ssl.SSLSocket fd=4060, family=AddressFamily.AF_INET, type=SocketKind.SOCK_STREAM, proto=0, laddr=('10.20.91.24', 8643), raddr=('129.206.7.231', 443)>

And the Python error:

Traceback (most recent call last):
              File "C:/Users/me/AppData/Roaming/QGIS/QGIS3\profiles\default/python/plugins\OSMtools\osm_tools.py", line 145, in run
                route.directions_calc()
              File "C:/Users/me/AppData/Roaming/QGIS/QGIS3\profiles\default/python/plugins\OSMtools\directions.py", line 137, in directions_calc
                layer_out = self._addLine(responses, values_list)
              File "C:/Users/me/AppData/Roaming/QGIS/QGIS3\profiles\default/python/plugins\OSMtools\directions.py", line 183, in _addLine
                values_list[i][0],
            IndexError: list index out of range

Any ideas what could be the problem(s)?

Operating System is Windows 10, x64 QGIS 3.0.0.

The Free plans limit to 40 requests per minute and you are exceeding the limit. The website lists out.

Free Plan

• 2.500 Requests per day
• up to 40 Requests per minute
• Directions API
• Geocoding API
• Matrix API
• Isochrones API
• POIs API

Most services have such limits on free plans. You will need to read the documentation or contact the plugin manager for support on this.
