REST connector cashing folder contains a data_.raw and a data_.xml. The result is no data

Hello,

I want to get metadate from my Azure datalake using their Blob API. 

I wasn't seeing any data in the Ingest storage so I turned on cashing to file, to try to see what's happening. 

There are three files in my cashing folder: 

• Data_.raw: The return of the call, i.e. my actual data. This look excellent, except that it's a .raw file. Contents:

  <?xml version="1.0" encoding="utf-8"?>
  <EnumerationResults ServiceEndpoint="https://xxxx.blob.core.windows.net/" ContainerName="datalake">
  	<Prefix>my_prefix</Prefix>
  	<Blobs>
  		<Blob>
              ....
          </Blob>
  	</Blobs>
  	<NextMarker/>
  </EnumerationResults>

   

• Data_.xml: Basically the same as the Data_.raw, but with the content of Data_.raw as the data of a value-element. The data also contains the XML header (so now the document has two headers) and the brackets have been encoded (i.e. all the `<` are now `<`). 

  <?xml version="1.0" encoding="utf-8"?>
  <Table_flattening_name>
  	<value>
          &lt;?xml version="1.0" encoding="utf-8"?&gt;
          &lt;EnumerationResults 
              ServiceEndpoint="https://xxxx.blob.core.windows.net/" 
              ContainerName="datalake"&gt;
              &lt;Prefix&gt;my_prefix&lt;/Prefix&gt;
              &lt;Blobs&gt;
                  &lt;Blob&gt;
                      ...
                  &lt;/Blob&gt;
              &lt;/Blobs&gt;
          &lt;NextMarker /&gt;
          &lt;/EnumerationResults&gt;
      </value>
  </Table_flattening_name>

   

• Data_transformed_1.xml: The result of my XSLT on Data_.xml

Data_transformed_1.xml contains one empty element, which is caused by Data_.xml being malformed. 

I can't really figure out what's going on. In other APIs I only had two files. Not sure what the Data_.raw file is doing, but everything would work if that file were Data_.xml. 

What could be causing this? Why is there a Data_.raw file? How can I fix this?
