Amazon MSK failed to associate 1 secret for cluster. The provided secret has an invalid schema

Question

We want to set up Username and password authentication with AWS Secrets Manager as per the documentation.

• We created a cluster in MSK
• Created a secret as well with name AmazonMSK_testmsk2 and with key as Password and Value as { "username": "alice", "password": "alice-secret" }

Still when we associate the secret with MSK we get the error Amazon MSK failed to associate 1 secret for cluster. The provided secret has an invalid schema

The troubleshooting documentation is not of much help either

Answer 1

Turns out you need to use Plaintext form.

Answer 2

This error can occur when one or more pre-requisites for creating the secret has not been followed. There are a few pre-requisites when creating the secret. AWS document for reference. Listing them below for quick access.

• Choose Other type of secrets (e.g. API key) for the secret type.
• Your secret name must have the prefix AmazonMSK_
• Your user and password data must be in the following format to enter key-value pairs using the Plaintext option.

    {
      "username": "alice",
      "password": "alice-secret"
    }
