    @Sahil Khurana I think you are using the API version v2.1 with the source string, which contains the location of your training files, and these training files might not be accessible.
    Are you using the format as mentioned in your request body?

      "source": "string",  
      "sourceFilter": {  
        "prefix": "string",  
        "includeSubFolders": false  
      "useLabelFile": false  

    Is this source an azure storage account with the required permissions?
    I think you can configure the same source string with the FOTT labeling tool and check if the training documents are loading before you submit the training request through the tool.
