sandbox error 20500 for getPrivileges

[pmaservizi]

hello, I'm trying to make a requesto to the sandbox endpoint getPrivileges for seler account, as instructed here: https://developer.ebay.com/api-docs/sell/static/seller-accounts/ht_get-selling-limits.html

however the response is always an error 500 with the following body:

{
    "errors": [
        {
            "errorId": 20500,
            "domain": "API_ACCOUNT",
            "category": "APPLICATION",
            "message": "System error."
        }
    ]
}

in the oauth token generation I included the scope

https://api.ebay.com/oauth/api_scope/sell.account

without it the response is code 403.

What am I missing? shoud I make some other requests before this?

thanks..

I have no experience with this call, but...

Did you create a sandbox seller account for this test?

The sandbox can not pull data from a real seller account.
