Amazon Athena CREATE EXTERNAL TABLE mismatched input 'external' invalidrequestexception

I am trying to create an external table in Amazon Athena. My query is the following:

CREATE EXTERNAL TABLE priceTable (
  WeekDay STRING,
  MonthDay INT,
  price00 FLOAT,
  price01 FLOAT,
  price02 FLOAT,
  price03 FLOAT,
  price04 FLOAT,
  price05 FLOAT,
  price06 FLOAT,
  price07 FLOAT,
  price08 FLOAT,
  price09 FLOAT,
  price10 FLOAT,
  price11 FLOAT,
  price12 FLOAT,
  price13 FLOAT,
  price14 FLOAT,
  price15 FLOAT,
  price16 FLOAT,
  price17 FLOAT,
  price18 FLOAT,
  price19 FLOAT,
  price20 FLOAT,
  price21 FLOAT,
  price22 FLOAT,
  price23 FLOAT,
  )

  ROW FORMAT DELIMITED
  FIELDS TERMINATED BY ';'
  LINES TERMINATED BY '\n'
  LOCATION 's3://myquicksighttestbucket/C1_SphdemDD_CANARIAS_20190501_20190531_v2'

Where the file in S3 is just a csv deliminted by semicolons. However, I get the following error:

line 1:8: mismatched input 'external'. expecting: 'or', 'schema', 'table', 'view' (service: amazonathena; status code: 400; error code: invalidrequestexception; request id: e524f7e6-39ca-4af7-9e39-f86a4d0a36c8; proxy: null)

Can anybody tell what I am doing wrong? Any help is much appreciated.
