title: How to find out what i'm doing wrong. Getting validation exception in timestream write Records with go sdk?
body: <p>As the title says, I'm trying to write a bunch of records to timestream, but I keep getting &quot;ValidationException&quot; without any further information, so I have no idea what should be fixed. The exact error response is:</p>
  <blockquote>
  <p>operation error Timestream Write: WriteRecords, https response error StatusCode: 400, RequestID: XXXXXXXXXXXXXX, ValidationException:</p>
  </blockquote>
  <p>It made me think that it was a multiline string and somehow the logging framework wasn't logging properly, but I tried splitting by \n and all I got was a size 1 list with the same text.</p>
  <p>Any ideas?</p>
