[jira] [Created] (NIFI-15184) PutMongo processor fails when _id field used as update key is a Document or Array

RAVINARAYAN SINGH created NIFI-15184:
----------------------------------------

             Summary: PutMongo processor fails when _id field used as update key is a Document or Array
                 Key: NIFI-15184
                 URL: https://issues.apache.org/jira/browse/NIFI-15184
             Project: Apache NiFi
          Issue Type: Bug
          Components: Core Framework
    Affects Versions: 2.4.0
            Reporter: RAVINARAYAN SINGH
            Assignee: RAVINARAYAN SINGH


When using the *PutMongo* processor in _update mode_ (with an update key defined), the internal helper method parseUpdateKey() does not handle cases where the _id field is a *Document* or *Array*.

 

According to MongoDB’s BSON specification, _id may be any valid BSON type, including nested documents and arrays. However, PutMongo assumes _id is either an ObjectId or a String
