Moving from source to synthetic_source

Elastic Stack Elasticsearch
1

Hi everyone,

I am moving set of indices from ES7 to ES8 with synthetic source. I added

"mappings": {
    "_source": {
      "mode": "synthetic"
    }
  }

this in the mappings. But now I am getting following error -

org.elasticsearch.common.util.concurrent.UncategorizedExecutionException: {"error":{"root_cause":[{"type":"illegal_argument_exception","reason":"field [add.category] of type [keyword] doesn't support synthetic source because it declares a normalizer"}],"type":"illegal_argument_exception","reason":"field [add.category] of type [keyword] doesn't support synthetic source because it declares a normalizer"},"status":400}

How should I go about it ? I am new to using synthetic_source. Is there any alternative to normalizer that we can use with synthetic_source?

I think your mapping is more than one single, no?

What is the full mapping?

For now to bypass this I added

"fields": {
                "stored": {
                  "type": "keyword",
                  "index": false,
                  "doc_values": false,
                  "store": true
                }
              }

Below is the complete mapping.

My guess is that:

"normalizer": "spr_lower_case_normalizer",

is not supported when you have synthetic source. The reason is that Elasticsearch can not rebuild the source data from something that has been transformed.
