This message in the data sync logs is coming from the Lightspeed rate limit. Lightspeed has set a low rate limit by default to manage the volume of data transmitted from their services. Please note that this rate limit is not within Clerk’s control. To address this, you have two options:

  1. Consider upgrading the rate limit service with Lightspeed.
  2. Alternatively, you may choose to wait for the synchronization process to complete.

429 Error - Too Many Request

This error means that Lightspeed made too many requests in a given amount of time and exceeded it’s rate limit. To address this we suggest to adjust the page size under your data sync settings in the backend.
