    <description>&lt;P&gt;Hi Team,&amp;nbsp;&lt;BR /&gt;&lt;BR /&gt;Am constantly running into this issue and not sure how to resolve it ...&lt;/P&gt;&lt;P&gt;&amp;nbsp;&lt;/P&gt;&lt;P&gt;I created a Gen 2 dataflow which ingests data from our UAT Dataverse environment and writes it to a Warehouse in Fabric. I have no issues ingesting any other Dataverse entities in the same manner.&amp;nbsp;&lt;BR /&gt;&lt;BR /&gt;However, the Contact Entity will never copy and will always error out with this message:&amp;nbsp;&lt;BR /&gt;&lt;BR /&gt;&lt;/P&gt;&lt;DIV class=""&gt;&lt;DIV class=""&gt;&lt;DIV class=""&gt;&lt;DIV class=""&gt;&lt;FONT size="2"&gt;&lt;FONT size="2"&gt;&lt;EM&gt;&lt;SPAN class=""&gt;There was a problem refreshing the dataflow.

      <description>&lt;P&gt;It may be because&amp;nbsp; of the sensitive data. since contact info is sensitive data.&lt;/P&gt;&lt;P&gt;&amp;nbsp;&lt;/P&gt;&lt;P&gt;&lt;SPAN&gt;If this post &lt;I&gt;&lt;STRONG&gt;helps&lt;/STRONG&gt;&lt;/I&gt;, then please consider &lt;I&gt;&lt;STRONG&gt;Accept it as the solution&lt;/STRONG&gt;&lt;/I&gt; to help the other members find it more quickly&lt;/SPAN&gt;&lt;/P&gt;</description>

      <description>&lt;P&gt;HI&amp;nbsp;&lt;a href="https://community.fabric.microsoft.com/t5/user/viewprofilepage/user-id/721460"&gt;@pws_flick&lt;/a&gt;,&lt;/P&gt;
&lt;P&gt;According to the error message, it seems related to fast copy in dataflow gen2, I'd like to suggest you take a look at the following document limitation part of your scenario meet to the limitations list.&lt;/P&gt;
&lt;P&gt;&lt;A href="https://learn.microsoft.com/en-us/fabric/data-factory/dataflows-gen2-fast-copy#known-limitations" target="_blank"&gt;Fast copy in Dataflows Gen2 - Microsoft Fabric | Microsoft Learn&lt;/A&gt;&lt;/P&gt;
&lt;P&gt;Regards,&lt;/P&gt;
