Querying MongoDB collection with nested data fails

To reproduce:

1. Create a json file called small.json with the below line:

{"_id":

{"$oid":"56a784b76952647b7b51c562"}

,"provenance":{"image":

{"case_id":"TCGA-TS2","subject_id":"TCGA"}

}}

2. Create a Mongo DB with the small.json as below:

mongoimport --db users --collection contacts --type small.json

3. Create a Mongo Query involving the nested data to confirm everything is fine.

use users;
db.contacts.find(

{ "provenance.image.case_id": "TCGA-TS2"}

);

This returns:

{ "_id" : ObjectId("56a784b76952647b7b51c562"), "provenance" : { "image" :

{ "case_id" : "TCGA-TS2", "subject_id" : "TCGA" }

} }

4. Create a Drill query for the same:

SELECT camic.provenance.image.case_id caseid
FROM mongo.users.`contacts` camic
WHERE caseid = 'TCGA-TS2';

The above query fails with the below error message.

Error: SYSTEM ERROR: NumberFormatException: TCGA-TS2

5. Please note the below returns the correct output:

SELECT camic.provenance.image.case_id caseid
FROM mongo.users.`contacts` camic;

-----------

-----------

-----------
1 row selected (1,135 seconds)

So the issue is with the WHERE clause:
WHERE caseid = 'TCGA-TS2"';
