Aspose.OMR Cloud API is throwing Bad Request error during template correction


I am attempting to generate a template using Aspose.OMR.Client tool. After marking up an image, when attempting to validate the template, a 400 bad request is thrown during the template correction process.
Source image upload completes successfully I can see it in “My files” .

In my aspose dashboard, the error response is:

Error: An error occured while connecting [No connection could be made because the target machine actively refused it]. Method: Run specific OMR task. Parameters: name ‘Arkusz Odpowiedzi.jpg’,actionName ‘CorrectTemplate’,param ‘Aspose.Omr.Cloud.DTO.OMRFunctionParam’,storage ‘’,folder ‘’

Please advise whether this is a server issue or if something wrong on my side.


We are sorry for the inconvenience. We have investigated the issue and fixed it. Please download updated Aspose.OMR Cloud SDK for .NET/Client from Github. It will resolve your issue.
