I keep getting There was a problem with an eBay internal system or process. Contact suppoty

I'm learning how to use ebay api via the sandbox and the api test tool but i keep getting this error : 

"errorId": 2003,
"domain": "ACCESS",
"category": "APPLICATION",
"message": "Internal error",
"longMessage": "There was a problem with an eBay internal system or process. Contact eBay developer support for assistance"

I've get the OAuth application token. And this problem takes place in multiples requests. 

Has this problem ever happened to you ? Do you know how to fix this ?

Hi @nai077,

Please make sure to use the correct access token when executing the API call. You can see the supported access token and scope for the call in the "OAuth scope" section. 

Also, all API calls are not supported in the Sandbox environment.  You can check the "Resource URI" section in API documentation to know if the API call is supported in the Sandbox environment. 

For example: https://developer.ebay.com/api-docs/buy/browse/resources/item_summary/methods/searchByImage#h2-input...

I tried with the application token and the users' one and it's the same on the search endpoint with the basic samples. 

Best Regards
