# 95421: Operator version conflict

Log Type: APPLICATION

Log Level: ERROR

## Description

The operator could not be updated due to a version conflict.

### Possible causes

* Operator was modified by another request since it was last fetched.
* The `If-Match` header does not match the current operator version.
* Concurrent updates to the same operator.

### Possible solutions

* Fetch the latest operator version before updating.
* Use the current ETag value in the `If-Match` header.
* Implement retry logic with fresh data on conflict errors.
