Error message

Not able to create pulsar admin: ${message}

What it means

Lazy-initialization failure in PulsarAdminSupplier.get: building the cached PulsarAdmin client (adminBuilder.build()) threw — bad service URL, TLS config, or auth settings — and the underlying exception message (with its class printed to stderr) is rethrown so the CLI command aborts; the admin builder configuration is the faulty input.
