The routerdb seems correctly loaded:

Any ideas?

I am also getting same error, can you please help me on this

Any updates for this issue?

[elecay]

To fix this issue I have done two things:

1. Update core libraries (see my PR: Updating core libraries #19)
2. Create a new RouterDb using Itinero's IDP tool: https://github.com/itinero/idp

For this last step, download the last stable build (look at the bottom here: http://files.itinero.tech/builds/idp/prereleases/)

Then, just follow the tutorial steps.

Example

To create a new RouteDb for Catalunya (Spain), download the OSM file from OpenStreetMap (https://download.openstreetmap.fr/extracts) database: https://download.openstreetmap.fr/extracts/europe/spain/catalunya-latest.osm.pbf

Then:

> ./idp --read-pbf catalunya-latest.osm.pbf --pr --create-routerdb vehicles=car --contract car --elevation --write-routerdb catalunya.routerdb

(Note: If you're using Linux, like me, make sure to change idp for IDP; note the uppercase. Also, make sure to make that file executable: chmod +x IDP)

Now, move catalunya.routerdb to the folder you have defined as routingfilepath in routing-api/src/Itinero.API/appsettings.json

Then:
> ./run.sh
