Reproducing the Issue

  1. Login to the BizX source instance 
  2. Admin Centre -> Instance Synchronization Wizard
  3. Under Instance Management -> Configuration Copy -> Select your desired Target  Instance to pair
  4. Once pairing is configured, try running a Test sync between Source and selected Target instances 
  5. Error is displayed


This is generally a temporary issue.


The following options can be tried:

  • Delete and setup fresh pairing between source and target instance.
  • Create in the Instance Sync wizard a new package with the same content as the package with the error. Then sync this new package to the target instance.
  • Or, this error message can also be ignored and the Actual Sync run can be attempted despite the test sync error. This is because the error often does not impact the actual sync run.

If issue still persists, please submit a Support case under the component LOD-SF-PLT-IST.
