GetItem API returns PictureDetails.PictureURL as null or "h" — Bug?

Subject: GetItem API returns invalid PictureURL ("h" or null)

Hello,

I am experiencing an issue with the **GetItem** call of the Trading API (Traditional API). When retrieving item details, sometimes the `PictureDetails.PictureURL` value returned is either `null` or a single character `"h"`, which seems completely invalid.

Example of the API call:
‌
‌<GetItemRequest xmlns="urnapis:eBLBaseComponents">
<RequesterCredentials>
<eBayAuthToken>REDACTED</eBayAuthToken>
</RequesterCredentials>
<ItemID>[some valid legacyItemId]</ItemID>
<IncludeSelector>Details,ItemSpecifics,ShippingCosts,PictureDetails</IncludeSelector>
</GetItemRequest>

Example response issue:
{
"PictureDetails": {
"PictureURL": "h"
}
}
or
{
"PictureDetails": {
"PictureURL": null
}
}

This happens intermittently on legitimate, active listings.

👉 Questions:
- Is this a known bug in the Trading API?
- Is there any workaround or specific parameter that should be added to ensure valid `PictureURL`?
- Could this be related to certain item conditions or listing formats?

Thank you for your support.

Best regards,
