This is the error message in Wiredtiger:

"errmsg" : "E11000 duplicate key error collection: test.some_col index: user_id_1 dup key: { : 1.0 }"

and this in ephemeralForTest:

"errmsg" : "E11000 duplicate key error dup key: { : 1.0 }"

The source code shows that adding the _indexName to the error string is marked as TODO.

// taken from btree_logic.cpp

Status dupKeyError(const BSONObj& key) {

    StringBuilder sb;

    sb << "E11000 duplicate key error ";

    // sb << "index: " << _indexName << " "; // TODO

    sb << "dup key: " << key;

    return Status(ErrorCodes::DuplicateKey, sb.str());

Thanks
