Having issues trying to boostrap a C3 7.0.1 instance from a Confluent cloud cluster. Confluent is failing to start with the following error message:

Here’s what my control-center-production.properties files looks like
# Confluent Control Center specific configuration
confluent.controlcenter.streams.sasl.mechanism=PLAIN
confluent.controlcenter.streams.security.protocol=SASL_SSL
bootstrap.servers=<cluster>:9092
confluent.controlcenter.streams.sasl.jaas.config=org.apache.kafka.common.security.plain.PlainLoginModule required username="secret" password="secret";
confluent.metrics.topic.max.message.bytes=8388608
confluent.controlcenter.mode.enable=management
confluent.controlcenter.data.dir=/data/kafka
# Confluent Schema Registry configuration for Confluent Control Center

confluent.controlcenter.schema.registry.basic.auth.user.info=secret:secret
confluent.controlcenter.schema.registry.url=https://<schema_registry>.aws.confluent.cloud
The key I’m using to boostrap from is associated to a service account which has, for now, the OrganizationAdmin role bound to it and the key was created after that role was bound to the user
confluent iam rbac role-binding list --role OrganizationAdmin --principal "User:sa-q2vgn6"
Principal | Email | Role | Environment | Cloud Cluster | Cluster Type | Logical Cluster | Resource Type | Name | Pattern Type
-----------------+-------+-------------------+-------------+---------------+--------------+-----------------+---------------+------+---------------
User:sa-q2vgn6 | | OrganizationAdmin | | | | | | |
I can also confirm that I have network connectivity to the cluster in question from the C3 instance:
# nc -vz <cluster> 9092
Ncat: Version 7.50 ( https://nmap.org/ncat )
Ncat: Connected to 10.233.102.211:9092.
Ncat: 0 bytes sent, 0 bytes received in 0.01 seconds.
Any ideas on why I am not able to retrieve the boostrap cluster id? Also, how do I get rid of those SLF4J bindings errors/warnings?
Thanks.
