I am currently trying to upgrade my elasticsearch stack from 7.17.7 to 8.9 but I run in the error in the upgrade assistant while trying to fix the deprecation issues, I get the following error

```auto
{"error":{"root_cause":[{"type":"mapper_parsing_exception","reason":"Root mapping definition has unsupported parameters: [_all : {enabled=false}]"}],"type":"mapper_parsing_exception","reason":"Failed to parse mapping [_doc]: Root mapping definition has unsupported parameters: [_all : {enabled=false}]","caused_by":{"type":"mapper_parsing_exception","reason":"Root mapping definition has unsupported parameters: [_all : {enabled=false}]"}},"status":400}

```

Anybody have any idea how do I fix this error?  
The ES stack is running on docker.
