Exporting secrets is failing

[vikram-yerneni]

Fellas,
I am running the plain command to export the secrets locally into a json file and its failing with below error:
`localMAC:bin root# ./vault-backend-migrator -export secret/ -file secrets.json
Reading all keys under secret/
Reading all secrets
Error reading secrets, err=Error making API request.

URL: GET https://myvault:8200/v1/secret
Code: 400. Errors:

• missing client tokeninvalid read on secret/
  Wrote /path/secrets.json
  localMAC:bin root# `

Anyone got clue on what's going on here??

Cheers
Vikram
