I have a record saved in dynamodb:

{
 ...
 st: {
   fs: {
      se: true
   }
  }
}

when I run the command to update st->fs->se in this record,

aws dynamodb update-item --table-name tableName --key '...' --update-expression 'SET #st.#fs.#se= :c' --expression-attribute-values '{":c": {"BOOL": false}}' --expression-attribute-values '{":c": {"BOOL": false}}'  --expression-attribute-names '{"#st": "st", "#fs":"fs", "#se": "se" }'

I got error:

An error occurred (ValidationException) when calling the UpdateItem operation: The document path provided in the update expression is invalid for update

How can I update the nested field?
