Internal failure occurred while resolving this field

Question

I'm getting this error from a graphql query that I'm polling from a website.  The query succeeds an arbitrary number of times and then returns this error.  The resolver is a simple SELECT from an RDS database.  There are no other details in the error response.  Is there some way I can get further insight into this?

Answer

I've run into a similar problem.  
  
I have found no way to see the actual error in Log Insights either.   
  
The error in the graph response looks something like this   
  
"errors":\[{"path":\["myFunction"],"data":null,"errorType":"InternalFailure","errorInfo":null,"locations":\[{"line":8,"column":5,"sourceName":null}],"message":"An internal failure occurred while resolving this field."}]  
  
This does not trigger fieldInError = 1 in any log nor does it log the message or errorType.
