Error message

e.getMessage()

What it means

doPublishConfig serializes the given data to JSON and publishes it to Nacos under the given dataId and group. Any NacosException from the publish is logged and rethrown as ShenyuException(e.getMessage()), so a failed config push aborts with the Nacos client's error text.

Solutions

1. Verify Nacos connectivity and server-addr/namespace/group settings.
2. Retry the publish from the dashboard once Nacos is healthy; transient timeouts are common.
3. Check Nacos server logs for write failures (e.g. disk full, Raft leader loss).
4. Inspect the wrapped message for the exact NacosException cause (e.g. errCode 400/403/503).

Example fix

// before
throw new ShenyuException(e.getMessage());
// after
catch (NacosException e) {
    throw new ShenyuException("Failed to publish dataId " + dataId + " to nacos", e);
}

if (!nacosReachable(serverAddr, timeoutMs)) { throw new IllegalStateException("Cannot publish: Nacos unreachable"); }

null

try { listener.doPublishConfig(dataId, data); } catch (ShenyuException e) { log.error("Nacos publish failed: {}", e.getMessage(), e); /* retry or requeue the config change */ }

When it happens

Trigger: Publishing plugin/selector/rule/attribute config changes to Nacos while the Nacos server is down, unreachable, times out, or rejects the write (auth failure, oversized payload, invalid group).

Common situations: Editing a rule in the shenyu dashboard while the Nacos cluster is degraded, network partition between admin and Nacos, wrong namespace, or Nacos auth enabled without credentials.
