Can't import to 2 instances on same metabase

[Karucida]

I want to import from exportfile the database with id 2 to 2 instances : 2 & 3 in your example :
DatabaseMapping:1=2 DatabaseMapping:2=3
My command:
sudo docker run --rm -v $PWD/data/:/data -v $PWD/appsettings.json:/app/appsettings.json elevate/elevate.metabase.tools Command=import InputFilename=/data/onreport2.json DatabaseMapping:2=2 DatabaseMapping:2=3

Only last value works:
DatabaseMapping:2=3

What i'm doing wrong?

Hola Carlos! Are you getting any errors? Or is it a case of the mappings not ending up as expected?
