Unable to calculate route - no tracker

Question

using the ArcGIS network Analyst, and having the network dataset, we have created a Geo Processing tool with arcpy and  python, generally the steps that we are trying are as follow:

we create the request: arcpy.nax.Route(super().config['network_data_source']

load the stops and barriers: routeRequest.load
then we solve and save the results in a zip and we publish it:

solverResult.saveRouteData(zipFile)
arcpy.na.ShareAsRouteLayers(zipFile,summary="RoutePlanner",tags="RoutePlanner",portal_folder_name=folderName,share_with="EVERYBODY")

so we have the route layer result on our portal and having the url for Navigator with routeitemID we can see the route on Navigator

BUT!! this is not the case always :
every while on Navigator we have this error that says "Unable to calculate route - no tracker!"

is there any clue why this might happen !?

Hi Moss,

In the cases where you are having issues with your routes, do they all have a large number of points? Or are there any other similarities among the problem routes?

Thank you,

Hi Kerri
we have always used the same mmpk in all the test we've done, which is the mmpk for the entire Italy but the test are done on the Rome city. and there are actually plenty routes that we've made both manually and via our GPTool that we could see them on Navigators, only in some cases we've this problem

thank you,

Hi Moss,

Good morning I have a few follow up questions for you.

* Are you able to manually create a route in ArcGIS Navigator using the same mmpk that you are using for your other routes?
* Also, does that mmpk cover the entire area you are trying to Navigate with your routes?
* And can you create a route with your custom tool with only a very small (less that 100 stops) and test it to see if it works?

The answers to these questions will help us know which direction to go next.

Thank you,

Kerri
