项目引入 sdk，调用getModelVersion 报错okhttp3.RequestBody okhttp3.RequestBody.create(java.lang.String, okhttp3.MediaType

[chengjiazhao]

代码如下
Liblib libLib = new LibLib(accessKey, secretKey);
GetModelVersionRequest getModelVersionRequest = new GetModelVersionRequest();
getModelVersionRequest.setVersionUuid(versionUuid);
VersionResponse modelVersion = libLib.getModelVersion(getModelVersionRequest);
