AddTaskAsync BatchErrorException: Operation returned an invalid status code 'BadRequest'

Question

I have implemented an Azure Batch example using a template based on the following sample:

https://github.com/Azure/azure-batch-samples/tree/master/CSharp/TextSearch

My solution creates a Job Manager task, which in turn creates multiple child tasks for each of my divisions. I am receiving a "BadRequest" error when I call batchClient.JobOperations.AddTaskAsync in the code below:

Console.WriteLine("Submitting {0} mapper tasks.", extracts.Count());

//The collection of tasks to add to the Batch Service.
List<CloudTask> tasksToAdd = new List<CloudTask>();

// Create Batch jobs
foreach (var extract in extracts)
{
// ToDo: Uncomment this
// extractService.SetStatus(extract.Id, WarehouseMasterConstants.eExtractStatus.Queuing);

string taskId = Helpers.GetSummarizeDivisionTaskId(extract.Id);
Console.WriteLine("Task Id: " + taskId);

string commandLine = string.Format("{0} {1}", SummarizeDivisionConstants.SummarizeDivisionTaskExecutable, extract.Id.ToString());
Console.WriteLine("Command Line: " + commandLine);
CloudTask unboundMapperTask = new CloudTask(taskId, commandLine);

//The set of files (exes, dlls and configuration files) required to run the mapper task.
IReadOnlyList<string> mapperTaskRequiredFiles = SummarizeDivisionConstants.RequiredExecutableFiles;

List<ResourceFile> mapperTaskResourceFiles = BatchHelpers.GetResourceFiles(containerSas, mapperTaskRequiredFiles);

unboundMapperTask.ResourceFiles = mapperTaskResourceFiles;

tasksToAdd.Add(unboundMapperTask);
}

//Submit the unbound task collection to the Batch Service.
//Use the AddTask method which takes a collection of CloudTasks for the best performance.
await batchClient.JobOperations.AddTaskAsync(this.jobId, tasksToAdd);      

I have confirmed by storage and batch credentials are correct and functioning.

Any suggestions in determining why I am getting a BadRequest would be appreciated.

Answer 1

Fixed the problem. My Task id included the executable name, which had "." in it. Replaced the "." with a "-" and it worked.
