Frequently Asked Questions

When you encounter the error statsigSDK> Event metadata is too large (max 4096). Some attributes may be stripped. in your logs, it indicates that the size of the metadata for a particular event has exceeded the maximum limit of 4096 characters when stringified. This limit is set by Statsig to ensure efficient data handling.

To resolve this issue, you should review the events you're logging and the associated metadata. You might be logging more information than necessary or there could be large data structures being included unintentionally. If you're unsure about what metadata is being sent, you can add debugging statements in your code to print out the metadata before it's sent to Statsig. This will help you identify any unusually large pieces of data. Once you've identified the cause, you can then modify your logging to reduce the size of the metadata. The goal is to log only the information that is necessary for your metrics and analyses.

Event metadata is usually included to filter your Metrics during analysis and define more contextual metrics. The topic of event-metadata and this limit are covered in the Statsig documentation.

This error is likely to be thrown when we log internal used performance logging events. It's not related to events your service logged with log_event. A patch will be released to fix this issue.
