405 HTTP method not allowed error on Connector Creation

[vinay-nadig-0042]

Hello,

I am trying to create a snowflake connector with the following configuration:

terraform {
  backend "s3" {}
  required_providers {
    kafka-connect = {
      source = "Mongey/kafka-connect"
      version = "0.2.3"
    }
  }
  required_version = "~> 0.12.4"
}

provider "kafka-connect" {
  url = var.connector_endpoint_url
  basic_auth_username = var.connector_username
  basic_auth_password = var.connector_password
}

resource "kafka-connect_connector" "snowflake_confluent_json_stg" {
  name = "snowflake_confluent_json_stg"

  config = {
    "connector.class" = "com.snowflake.kafka.connector.SnowflakeSinkConnector"
    "snowflake.topic2table.map" = "dev.AccMd.v1:DEV_ACCMD_V1"
    "tasks.max" = "3"
    "topics" = "dev.AccMd.v1"
    "buffer.flush.time" = "180"
    "snowflake.url.name" = "<REDACTED>"
    "snowflake.database.name" = "TEST_DB"
    "snowflake.schema.name" = "kafka"
    "buffer.count.records" = "100000"
    "snowflake.user.name" = "KAFKA_STG"
    "name" = "snowflake_confluent_json_stg"
    "errors.tolerance" = "all"
    "value.converter" = "com.snowflake.kafka.connector.records.SnowflakeJsonConverter"
    "key.converter" = "org.apache.kafka.connect.storage.StringConverter"
    "buffer.size.bytes" = "10485760"
  }

  config_sensitive = {
    "snowflake.private.key" = var.snowflake_private_key
    "value.converter.basic.auth.credentials.source" = "USER_INFO"
    "value.converter.basic.auth.user.info"  = var.schema_registry_basic_auth
  }
}

This is the first time that the connector is being created. When I run a terraform apply, I get the following error message(console output):

$ terraform apply -auto-approve
kafka-connect_connector.snowflake_confluent_avro_stg: Creating...
kafka-connect_connector.snowflake_confluent_json_stg: Creating...
Error: Create connector : {"error_code":405,"message":"HTTP 405 Method Not Allowed"}
  on main.tf line 18, in resource "kafka-connect_connector" "snowflake_confluent_json_stg":
  18: resource "kafka-connect_connector" "snowflake_confluent_json_stg" {
Error: Create connector : {"error_code":405,"message":"HTTP 405 Method Not Allowed"}
  on main.tf line 46, in resource "kafka-connect_connector" "snowflake_confluent_avro_stg":
  46: resource "kafka-connect_connector" "snowflake_confluent_avro_stg" {

It looks like this is because the HTTP request that is sent is a PUT request rather than a POST request for creating the resource.

I can see the following logs on the server side

[2020-10-21 10:36:52,473] ERROR Uncaught exception in REST call to /connectors/connectors (org.apache.kafka.connect.runtime.rest.errors.ConnectExceptionMapper)

javax.ws.rs.NotAllowedException: HTTP 405 Method Not Allowed

Any idea why this is happening and how it can be fixed?

Terraform version - 0.12.4
kafka-connect version - 0.2.3

"connectors" are overwrapping? Is it correct?
/connectors/connectors
