Hey! I am trying to make a simple GrowthBook metrics analysis but I get some errors. We are using Amplitude as our product analysis platform so I had to export our data to AWS Athena (I am not even sure if we did this right but GrowthBook seems to think it is?). Anyway, I just create a metric, "Doctor List", which is supposed to get all the "Doctor List" events that already exist, but when I try to analyse this metric by clicking on "Run analysis" I get the following error: line 14
11 mismatched input '$'. Expecting: '*', <expression>.  The SQL query that GrowthBook is generating is:
-- Last 90 days - Doctor List Metric
WITH
  __metric as ( -- Metric (Doctor List)
    SELECT
      anonymous_id as anonymous_id,
      1 as value,
      m.timestamp as timestamp,
      m.timestamp as conversion_start,
      m.timestamp as conversion_end
    FROM
      (
        SELECT
          user_id,
          $ amplitude_id as anonymous_id,
          event_time as timestamp
        FROM
          $ events
        WHERE
          event_type = 'Doctor List'
      ) m
    WHERE
      m.timestamp >= from_iso8601_timestamp('2023-01-12T23:11:24.843Z')
      AND m.timestamp <= from_iso8601_timestamp('2023-04-16T23:11:24.843Z')
  ),
 .......
Line 14 (where the error is) is basically this: 
$ amplitude_id as anonymous_id,
