We are investigating the issue and will share our findings with you soon.


Please double check that you have download/clone the submodule aspose-omr-cloud-demo-data as well and you have put client Id/secret and updated basepath version in test_config_sample.json and also rename the configuration file to test_config.json.

   "app_key"  : "xxxxxxxxxxxxxxxxxxxxxxxxxxxx",
	"app_sid"   : "xxxxx-xxxx-xxxx-xxxx-xxxxx",
	"base_path" : "",
	"data_folder" : "Data"

To clone the submodule aspose-omr-cloud-demo-data you can use the following git command

git clone --recurse-submodules

or you can simply download directly to another folder and then copy it to the .NET SDK folder.
