[BUG] Cannot change snapshot policy repository

[opoplawski]

Describe the bug

I have the following snapshot policy that references a repository that no longer exists:

However when I go to edit it, the repository shows as the one that does exist:

but when it runs it fails due to the missing repository:

org.opensearch.repositories.RepositoryMissingException: [my-fs-repository] missing

OpenSearch Version
2.19.1

Dashboards Version
2.19.1

Host/Environment (please complete the following information):*

• OS: AlmaLinux 8.10
• Browser and version Firefox 128.9.0

Additional context

I deleted the previously existing my-fs-repository and replaced it with osnap without changing the policy. Then tried to change the policy to use osnap but apparently that does not take.

I'm trying to update the policy manually with:

POST _plugins/_sm/policies/weekly-snapshot?if_seq_no=555416069&if_primary_term=165
{
     "description": "",
    "creation": {
      "schedule": {
        "cron": {
          "expression": "0 20 * * *",
          "timezone": "America/Los_Angeles"
        }
      }
    },
    "deletion": {
      "schedule": {
        "cron": {
          "expression": "0 20 * * *",

        }
      },

      }
    },

      "indices": "*",
      "repository": "ossnap"
    },
    "schedule": {

    },
    "enabled": true,

        "deletion": false,
        "failure": true,
        "time_limit_exceeded": false
      }
    }

}

but I get:
