Hi,

I am trying to import the data from MongoDB to Elastic. As part of that, I am using the "logstash-input-mongodb" as an input plugin. But I am facing the below error while importing it.

## Conf file:

input {  
mongodb {  
uri =\> 'mongodb://localhost:27017/dbname'  
placeholder\_db\_dir =\> '/tmp'  
placeholder\_db\_name =\> 'logstash\_sqlite.db'  
collection =\> 'Entity$'  
batch\_size =\> 5000  
}  
}  
output {  
elasticsearch {  
hosts =\> "[http://localhost:9200](http://localhost:9200)"  
index =\> "suspicious"  
}  
}

## MongoDB data set:

{ "\_id" : "04ec4fb4-f49c-4136-a980-3d7fe3bf1635", "name" : "bob" }  
{ "\_id" : "16172af2-e56f-4573-9940-f762a4fbb4ba", "name" : "foo" }

## Error:
