Error in Logstash Pipeline

I am getting this error when trying to run my Logstash pipeline. I would appreciate any help!! Thanks so much!

You need to tell logstash which input you are trying to configure. I would start with

input {
    mongodb {
        uri => 'mongodb://username:password@152.3.22.155'
        placeholder_db_dir => '/Users/caitlyn/desktop/logstash-7.11.2/bin'
        placeholder_db_name => 'logstash_sqlite.db'
        collection => 'ml4p'
        batch_size => 5000
    }
}

I do not think the mongodb input is installed by default so you will need to install it.

Thank you! That worked but now I am getting this error:

WARN -- : MONGODB | Failed to authenticate to 152.3.22.155:27017: Mongo::Auth::Unauthorized: User cait (mechanism: scram) is not authorized to access admin (auth source: admin, used mechanism: SCRAM-SHA-1, used server: 152.3.22.155:27017 (STANDALONE)): Authentication failed. (18: AuthenticationFailed)

Do you have to have insert privileges in MongoDB for it to work?

It needs to be able to .connect to the database and to .find entries. I do not know anything about the mongodb permissions model so I cannot say what privileges it needs.

Thank you for your help!
