Unable to submit UploadSiteHostedPictures with Postman

[pepejf]

I'm trying to understand the UploadSiteHostedPictures call using postman before migrating the login into my software. However, I can't seem to make the call work. I'm following exactly the documentation from the eBay API guide.  I keep getting the error :

<ShortMessage>XML Parse error.</ShortMessage>

<LongMessage>XML Error Text: "{0}".</LongMessage>

Here is what I have configured in Postman. Can someone see the issue and explain how to correct it please?

Here is the value of the attachment_xml variable:

<?xml version="1.0" encoding="UTF-8"?>
<UploadSiteHostedPicturesRequest xmlns="urnapis:eBLBaseComponents">
<PictureName>myphoto</PictureName>
<PictureSet>Standard</PictureSet>
<ExtensionInDays>0</ExtensionInDays>
</UploadSiteHostedPicturesRequest>

I found the issue. The order of the form data is important. XML Payload must be before the image in the form body. I just inverted the two entries and it worked.
