Dynamics API is broken

Question

Hello, Our system is an Java application which integrates with Dynamics CRM, in the last few years we havent made any change, from last week, the following API is broken. I have two issues. **First issue,** since we havent made any change, but the API is broken, I believe Dynamics must have made some change on their end.

String url = "https://{client name}.crm.dynamics.com/api/data/v9.1.0.6228/z2t_models?fetchXml=<fetch version="1.0" output-format="xml-platform" count = "5000" page="1"><entity name="z2t_model"><attribute name="z2t_modelid" /><attribute name="z2t_machinekind" /><attribute name="z2t_name" /></entity></fetch>";
restTemplate.exchange(url, HttpMethod.GET, entity, String.class);

The API returns 500 internal error, the error message of response:

{"error":{"code":"0x0","message":"Unexpected character encountered while parsing value: \ufffd. Path '', line 0, position 0."}}

But I can call this API successfully using postman, it isn`t helpful from the error message. I am wondering what change I should make in order to call this API successfully.

Second issue: I made some change, removed the parameters from original url, and sent the parameters in the exchange method, for example,

String url = "https://{client name}.crm.dynamics.com/api/data/v9.1.0.6228/z2t_models";
String param = "<fetch version="1.0" output-format="xml-platform" count = "5000" page="1"><entity name="z2t_model"><attribute name="z2t_modelid" /><attribute name="z2t_machinekind" /><attribute name="z2t_name" /></entity></fetch>";
Map<String, String> params = new HashMap<>();
params.put("fetchXml", param);
restTemplate.exchange(url, HttpMethod.GET, entity, String.class, params);

It returns 200, but it returns a lot more information in response body which will causes out of memory issue on our end.

I will appreciate any help here, thanks!
