Unable to update source from service.db to datastore

I’m trying to update soon to be retired service.db to datastore by replacing:

props: {
    db: "$.service.db",
  },

with

props: 
{
   db: { type: "data_store"},
  },

However, when I try to do this through the source UI, I getting the following error:
Configured props db is required

Am I doing something wrong?

@eaptdudfield I apologize for the confusion. In our communication to users I should have specified that $.service.db is still accessible in event sources. You don’t need to make any changes if you’re just using $.service.db in event sources.

It will be deprecated from workflows. I’ll reach out on that original thread to clarify that.
