failed to RSA encrypt the plaintext: crypto/rsa: message too long for RSA key size

My config.hcl:

# Benchmark config options
vault_addr = "http://localhost:8200"
vault_token = "root"
vault_namespace = "root"

test "transit_decrypt" "transit_decrypt_test" {
    weight = 100
    config {
        payload_len = 191
    }
}

I run ./vault-benchmark run -config=config.hcl and it returns an error:

vault-benchmark version is 0.3.0

Reproduce the failure with the provided config.hcl using ./vault-benchmark run -config=config.hcl, focusing on target setup for the transit_decrypt test with payload_len = 191. Trace where the RSA encryption error is surfaced and define completion as handling this configuration without the reported message-too-long failure.
