My plugin will NOT START (and I suspect it's MongoDB) and I don't know why

While you are waiting for getting help, here are some tips to improve your experience:

Code is much easier to read if posted with syntax highlighting and proper formatting.

If nobody is calling back, that usually means that your question was not well asked and hence nobody feels confident enough answering. Try to use your time to elaborate, provide details, context, more code, examples and maybe some screenshots. With enough info, someone knows the answer for sure.

Don't forget to close your thread using the command </help-thread close:1027500463647621170> when your question has been answered, thanks.

Reading this, my connection returns null from vault, and I severely suspect that to come from databaseConnection variable (MongoDBDatabaseConnection.kt, because of unfixed past experiences),
I don't know why it's just returning null though, didn't handle that with a try/catch most likely.

you're probably wondering some questions:

1. well, did you confirm the indention of the YAML files? and does the variables of mongodb-database-collection and others exist? perhaps you're using another file on accident.
   I have confirmed and this is not the case.

2. you probably put in the wrong collection/database, check again perhaps?
   I have tried checking multiple times, even recreating my cluster, and it doesn't work thus returning null.

I uploaded your attachments as gist. That way, they are easier to read for everyone, especially mobile users 👍

[feral dove]

thank you tj-bot

VaultEconomySupport.kt line 21 refers to MongoDBDatabaseConnect (val databaseConnect: MongoDBDatabaseConnect = greenBank.mongoConnect!!) so my databaseConnect is the imposter here

and we all know the impostor is sus

Changed the category to Database.

so here in GreenBankMain.kt this is how I connect to the database

mongoConnect = MongoDBDatabaseConnect(this)
        if (mongoConnect!!.connection != null) {
            val shouldUseAsyncConnection = databaseConfigFile!!.getBoolean("should-use-async-connection")
            val connectDatabaseAsync: BukkitRunnable = object : BukkitRunnable() { override fun run() { mongoConnect!!.createConnection() } }
            when {
                shouldUseAsyncConnection -> connectDatabaseAsync.runTaskAsynchronously(this)
                !shouldUseAsyncConnection -> connectDatabaseAsync.runTask(this)
            }
        }
        registerAll(this)

Detected code, here are some useful tools:

Formatted code

mongoConnect = MongoDBDatabaseConnect(this ) if (mongoConnect!!.connection != null ) {
  val shouldUseAsyncConnection = databaseConfigFile!!.getBoolean("should-use-async-connection") val connectDatabaseAsync : BukkitRunnable = object : BukkitRunnable() {
    override fun run() {
      mongoConnect!!.createConnection() }
  }
  when {
    shouldUseAsyncConnection -> connectDatabaseAsync.runTaskAsynchronously(this ) !shouldUseAsyncConnection -> connectDatabaseAsync.runTask(this ) }
}
registerAll(this )

here's how I connect to my database (createConnection()) and read n' write to the collection (getConnection())

This is in MongoDBDatabaseConnect.kt

override fun createConnection(): MongoClient = MongoClients.create(MongoClientSettings.builder()
            .applyConnectionString(ConnectionString(greenBank.databaseConfigFile!!.getString("mongodb-connection-uri")))
            .serverApi(ServerApi.builder().version(ServerApiVersion.V1).build())
            .build())

    override fun getConnection(): Any? {
        val mongoDatabase = createConnection().getDatabase(greenBank.databaseConfigFile!!.getString("mongodb-database-name"))
        return mongoDatabase.getCollection(greenBank.databaseConfigFile!!.getString("mongodb-database-collection"))
    }

  val mongoDatabase = createConnection().getDatabase(greenBank.databaseConfigFile!!.getString("mongodb-database-name")) return mongoDatabase.getCollection(greenBank.databaseConfigFile!!.getString("mongodb-database-collection")) }

[feral dove]

then i use this

val collection = (connection as MongoCollection<Document>)

to produce getters and setters for collection and type cast it as a mongodb collection

in MongoDBDatabaseConnect.kt aswell

~
~
~
and then in VaultEconomySupport.kt,
I access MongoDBDatabaseConnect.kt via GreenBankMain.kt

private val databaseConnect: MongoDBDatabaseConnect = greenBank.mongoConnect

but getCollection() (formally known as collection in kotlin) returns null for a weird reason

[feral dove]

if you'd still like to check out exactly what causes this i have sent files above

please note that i'm not and I mean I AM NOT handling the exception, it's doing that on its own because VaultEconomySupport.kt returned null here

[feral dove]

var mongoConnect: MongoDBDatabaseConnect? = null

this is mongoConnect in GreenBankMain.kt (global variable, out of methods)
and it's declared at onEnable()

mongoConnect = MongoDBDatabaseConnect(this)

this refers to the GreenBankMain.kt

so should I initialize mongoConnect when declared at the global variable, should I declare at onLoad(), or what should I do exactly?
