@Oleksandr Budnyk, Thanks for posting in Q&A. Based as I know, the ConditionNotMet
error in the UpdateRelationships
action occurs when the specified condition is not met for the requested operation. This error can occur when trying to remove a relationship that does not exist. You can check if the relationship exists before attempting to remove it to avoid this error. And if there's any information wrong.
Hope the above information can help.
