title: Power BI - "Expression.Error: The column of the table wasn't found
body: <p>This error pops up randomly when I import data to Power BI using Supermetrics API about a day after when trying to refresh.
  For example, using Adobe Analytics data, when I try to refresh my dashboard a day later, I sometimes get this error, saying <a href="https://i.stack.imgur.com/FViiI.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/FViiI.png" alt="enter image description here" /></a></p>
  <p>When I click on &quot;Go to error&quot; it takes me to Changed type step, but I see that the code remains the same as I first imported it.
  Going to Navigation step, I see that the data has changed, but I don't know why, since I haven't changed anything since I pulled data to Power BI.</p>
  <p>What it used to look like:

  <p>vs what it looks like now

  <p>I have tried seeking help from Microsoft community, but no use, since most topics suggest changes to the code, which I haven't done.</p>
