Uploading file to aspose-cells pod through backend is throwing error (using on premise approach)

We are trying to upload a file to aspose-cells pod from backend pod. We are using on Premise approach. Please see below axios call that we are making for the same(replace namespace) :

let data = new FormData();
            const baseUrl = 'http://aspose-cells-cloud.<nameSpace>.svc.cluster.local';
            if(!stream) {
                stream = fs.createReadStream(inputFilePath); // inputFilePath is received as arguement
            }
            data.append('File', stream);
            let config = {
                method: 'put',
                url: baseUrl + '/v3.0/cells/storage/file/%2Fdata%2F' + inputFileName + '?storageName=First%20Storage',
                headers: {
                    'accept': 'application/json',
                    'Content-Type': 'multipart/form-data',
                    ...data.getHeaders()
                },
                data: data
            };
            await axios(config)
.then(function (response) {
                    console.log('aaa', response);
                    if (response.status === 200) {
                        logger.info(`File uploaded successfully.`);
                    }
                    else {
                        logger.error(`Error while uploading file. Response Status Code: ${ response.status }`)
                    }

                })
                .catch(function (error) {
                    throw error;
                });

We are getting 200 ok but in the response.data we are also getting errors in the array. When we console log the errors array we got following response:

Errors: [
    {
      Code: 'errorLocalStorage',
      Message: "Local Storage exception: Access to the path '/data/qqqqq.xlsx' is denied.",
      Description: 'Operation Failed. Permission denied',
      InnerError: [Object]
    }
  ]

@rajatdpw,
How can you configure disk mapping for containers?
