How to build index for already present property?

问题

When I am updating my schema, I created a new property(say A) but I forgot to build index. Without knowing that, I have tried to add the value for that property resulted in

    :> g.V().hasLabel('AA').has('active',true).property('A','ok').count()

** Could not find a suitable index to answer graph query and graph scans are disabled: [(~label = user)]:VERTEX**

    :> g.V().hasLabel('AA').has('active',true).has('A','ok').valueMap()

But when I do valueMap by traversing it with other indexed property then the newly created property value got added.

Now I am trying to build the index by getting the already created property, but it is throwing an error saying

Error in /tmp/scripts/dbscripts/camp/campaignTypeSchema/run.groovy at [3: :> @myScript1] - null
