Overview

Follow this guide to learn more about common Facebook (Meta) error codes that you may encounter and how to troubleshoot these issues.

Common Internal Error Codes:

-1 (Warning):

This code indicates that while the Facebook destination did not return an error, there was something unusual about the request.

For example, if Snapchat requires a product ID in an event but the incoming event lacked one, Snapchat might still accept the request without an explicit error. However, you may still see this warning to highlight that the event may not be processed as expected.

-100 (Timeout):

This error means there was an attempt to send your event to the Facebook destination, but the destination took too long to respond. As a result, we cannot confirm whether the event was successfully received or processed.

-500 (Unexpected Error):

A -500 error signals that something went wrong, but the root cause is unclear. This could be due to a bug in the code or a network error that led to a canceled request.
