AFAIK only koxudaxi/local-data-api:latest supports providing custom SECRET_ARN environment variable. Within koxudaxi/local-data-api:0.6.12 and probably older versions, if the SECRET_ARN does not equal the default ARN of arn:aws:secretsmanager:us-east-1:123456789012:secret:dummy then rds-data API commands raise the following error message:

Error fetching secret {secret_arn} : Secrets Manager can’t find the specified secret (Service: AWSSecretsManager; Status Code: 400; Error Code: ResourceNotFoundException; Request ID:  00000000-1111-2222-3333-44444444444)
