Data Migration From Tokumx 1.5 To Percona MongoDB Server 3

Question

I want to migrate from TokuMX 1.5 to Percona MongoDB server 3.11. Following Data Migration guide provided by percona . which works fine, but at:

Step 12 : Restore the indexes (this may take a while). This step will remove clustering options to the collections before inserting.

$./psmdb_restore_indexes.js --eval " data='/your/dump/path/tokumxIndexes.json' "

My migration fails and gives the following error:

/mnt/tokumx-bkup/tokumxIndexes.json
