This refers to the REST API feature Pull dedicated to the Repository management :

https://docs.automic.com/documentation/webhelp/english/AA/12.3/DOCU/12.3/REST%20API/Automation.Engine/index.html?overrideUrls=../Automation.Engine/swagger.json,../Continuous.Delivery.Automation/swagger.json,../Analytics/swagger.json,../Infrastructure.Manager/swagger.json#/repositories/pull

 

 

Environment

Release : 12.3  Component : AUTOMATION ENGINE

 

Cause

This is bug in current 12.3 Version.

If the pull contains too many changes compared to the current version, this error is likely happen.

Resolution

A. This is a bug which will be fixed in a near version.

B. There are 2 workarounds:

1: Apply the changes in smaller batches, 1 commit at a time, with a smaller set of objects. Push the change in the repo from the source, and then pull the changes into production. Repeat this until all changes are propagated.

2. Apply all changes at once and re-init client from branch.
