### Problem Description

When put repository using PutRespository API for an existing repository, NullPointerException was thrown, short stack shows as below
```

### Steps to Reproduce

I've created an IT to reproduce this issue in [#85551](https://github.com/elastic/elasticsearch/pull/85551), steps can be described as following:
- put repository using `RestPutRepository` API and make sure non-master node failed to create repository.
- restart master let one of the previous non-master node become master
- put the same repository using the `RestPutRepository` API.
