Failed to send agentInfo. result not set

Error message

Failed to send agentInfo. result not set

What it means

Same null-result failure path as error 584 but logged when agentInfo or agentInfo.getAgentInformation() is null, so no agent details can be included in the message. The send attempt returns false and will be retried later.

Solutions

1. Verify pinpoint.config provides agentId, applicationName and that AgentInformation is built at startup
2. Check the Builder wiring: ensure agentInfo passed to sendAgentInfo carries getAgentInformation() != null
3. Confirm the collector responded within 3 seconds; if network latency is the root cause, the null path wouldn't apply — treat config first
4. Enable DEBUG logging on AgentInfoSender to trace what is being sent

Example fix

// before
AgentInfoSender.Utils.sendAgentInfo(sender, null);
// after
AgentInfo agentInfo = new AgentInfo(agentInformation, jvmInfo, ...);
AgentInfoSender.Utils.sendAgentInfo(sender, agentInfo);

if (agentInfo == null || agentInfo.getAgentInformation() == null)
    throw new IllegalStateException("AgentInformation must be populated before sending");

boolean isSendable(AgentInfo a) { return a != null && a.getAgentInformation() != null; }

When it happens

Trigger: future.get(3000ms) returned null ResultResponse while the AgentInfo object itself or its embedded AgentInformation is null — usually a construction/configuration defect rather than a network issue.

Common situations: Agent misconfiguration where agentId/applicationName/hostname were never populated into AgentInformation; programmatic use of AgentInfoSender.Builder with missing fields.

Understand the failure class

Background: "invalid response format", "malformed payload", "missing data field": when an API returns 200 but the response shape is wrong — this error's family across 23 libraries.
