Null value resolved for non-null field resolver Error

[satwikkansal]

I think there are some ResolverEvents that have null set for resolver field.

Query to replicate:

resolverEvents(first:2, where:{ resolver_not: null, blockNumber_gt: 14891090}) {     	
   id
   transactionID
  blockNumber
  resolver { 
    id     	
  }
}

If I comment out the resolver fields, and run the same query, this is what I get,

Interestingly, transaction IDs for both the records are same i.e. 0xc5141297ff039da6fef3fa6b7903d35ac1e7ba250a053040974e659d264bd97f, and the second one for some reason has resolver set to null.

Since the graph doesn't support filter on nested entries, any suggestions on how to get around this?
