Failed to execute bulk item cannot be changed from type

Hi

I am getting the following error while reindexing the elastic index using postman.

The crazy thing is it happens infrequently and without any pattern. I tried reindexing 8 times using postman and it failed 2 times and worked remaining 6 times, only the target index name was changed for each request.

POST _reindex
{
  "source": {
    "index": "rcyc"
  },
  "dest": {
    "index": "temprcyc1"
  }
}

Success

POST _reindex
    {
      "source": {
        "index": "rcyc"
      },
      "dest": {
        "index": "temprcyc2"
      }
    }

Failed

Target is both times an empty index. The mapping of suiteAvailability is long in source

"suiteAvailability": {
                        "type": "long"
                    }

We are using a cluster of 3 Elasticsearch nodes. reindex is called to the main server.

Hi what is the type of the field suiteAvailability in the source index ?

[Jishnu_Prathap]

in source suiteAvailability is long type. destination index is empty.

"suiteAvailability": {
                        "type": "long"
                    }
