Root mapping definition has unsupported parameters (mapper_parsing_exception)

I am new to Elasticsearch. I have tried different solution provided on Stack Overflow and other websites but they didn't work for me that's why I am posting this question.

I am trying to add tokenizer": "uax_url_email" so that I can easily search email with query.

But when I am setting the mapping it Elastic Search is giving me this error:

Root mapping definition has unsupported parameters (mapper_parsing_exception)

I have tried to delete the index and recreate it but it also didn't help.
