get offer data after migration

[alikocha-53]

Hello, I successfully migrated a single offer that was posted by an eBay account. Now, I am trying to obtain details of this offer and the listing. Retrieving product details using

/inventory/v1/inventory_item/{sku}

returns the correct data. However, both of the offer requests,

/inventory/v1/offer?sku={sku}&marketplace_id=EBAY_DE
/inventory/v1/offer/{offer_id}

result in a 500 error:

{"errors":[{"errorId":25001,"domain":"API_INVENTORY","subdomain":"Selling","category":"System","message":"Ein Systemfehler ist aufgetreten."}]}

What am I doing wrong?

Hi developer_support@ebay, 

Could you please help me resolve this?

The headers for the two should be the same.

Be sure that the SKU is correct as it is case sensitive. If you have spaces or other special characters you may need to create an escaped data string for use in a URL.

Do you have any more information in the response?
