For now, the only way to solve that I believe is at index time or using an ingest script processor.

I opened the following issue for discussion:

> <https://github.com/elastic/elasticsearch/issues/23839>
>
> \`\`\`
> DELETE test
> PUT test
> {
> "mappings": {
> "my\_type": {
> "propert…ies": {
> "status\_code": {
> "type": "text",
> "null\_value": "NULL" 
> }
> }
> }
> }
> }
> \`\`\`
> 
> This is now failing in 5.x.
> 
> Either it's a bug and we should still support it or we should document it as a breaking change for people who are moving their \`string\` mapping to \`text\`.
> 
> Thoughts?
