PROBLEM: Connection error. Your VPC must be able to connect to Lambda

Hi

We created a lambda function with MSK trigger, it says:

* Last processing result: **PROBLEM: Connection error. Your VPC must be able to connect to Lambda and STS, as well as Secrets Manager if authentication is required. You can provide access by configuring PrivateLink or a NAT Gateway.**

We don’t have/use STS, Secret Manager.
We have NAT gateway and ProvateLink
