Failed to import osm file to neo4j

[jkarippery]

Hello,
I am new to neo4j.
I got an error while import .osm file to neo4j.

error I got : Failed to invoke procedure spatial.importOSM: Caused by: java.io.FileNotFoundException: .\import\niedersachsen_01.osm (The filename, directory name, or volume label syntax is incorrect)

what I did explain below.

• download .osm.pbf file from Geofabrik Download Server
• convert .osm.pbf file to .osm file using osmconvert
• i am using neo4j desktop v 1.4.1
• download spatial plugin: neo4j-spatial-0.27.2-neo4j-4.2.3-server-plugin.jar
• create new dbms in neo4j
• CALL spatial.procedures it work fine
• copy my osm file to ...\dbmss\dbms-9...\import
• CALL spatial.importOSM('.\import\niedersachsen_01.osm')

please help me

Thank you
