Amazon Mobile Analytics JS SDK自定义事件日志失效问题咨询

Hey there, let's troubleshoot why your Amazon Mobile Analytics custom events aren't being recorded properly—even though you're getting a well-formatted response. Here are targeted checks and fixes to try out:

• Fix your attributes format first
  Looking at your response, the attributes field is a string: "{'Name1':'Value1', 'Name2':'Value2'}". The JS SDK expects a plain JavaScript object here, not a stringified JSON. If you're passing a string instead of an object, the backend can't parse the attributes correctly, so the event gets dropped. Try changing your event call to pass an actual object like this:

  // Correct way to pass attributes
  mobileAnalyticsClient.recordEvent('iPhone', {
    Name1: 'Value1',
    Name2: 'Value2'
  }, {}); // Empty object for metrics if you don't need them
  

• Check your eventType for extra quotes
  Your eventType is "'iPhone'" (with surrounding single quotes). Most likely, the extra quotes are causing the backend to misclassify the event. Use a clean string like "iPhone" instead of wrapping it in quotes.

• Force immediate event submission
  The Amazon Mobile Analytics JS SDK uses batch processing by default—it caches events locally and sends them in batches after a delay. If you're testing, manually trigger submission to rule out queueing issues:

  mobileAnalyticsClient.submitEvents();
  

• Validate your session integrity
  Confirm the session.id in your response corresponds to an active, valid session. If the session expired or wasn't initialized correctly, events tied to it won't be logged. Try reinitializing the session or checking if the startTimestamp aligns with your current session timeline.

• Check browser console for hidden errors
  Open your browser's DevTools Console tab—look for silent errors like CORS issues, missing permissions, or SDK initialization warnings. These might not break the response format, but they can block events from being sent to the backend.

• Verify IAM permissions
  Double-check that your IAM role has the mobileanalytics:PutEvents permission. Even if you get a success response, insufficient backend permissions can lead to events being discarded without an explicit error.
