Workflow step with WorkQueueService Add Method debug

I’ve an easy 3-step Workflow executed by UI action button, which is working on Flash version 2016. It loads data, transforms data and adds transformed data to WorkQueue (class Mail). But there is nothing added to that WorkQueue - it’s empty. There is no error in the Workflow debug log - see attached log. Is there any better way how to debug WorkQueueService on HTML5 ?
Thank you.

Did you try tracing the workflow to see that some data are really added to the work queue?

Yes I tried it, but the last step 03 (AddToQueue) is missing in the trace and there is no error shown in previous step.

Can you provide the XSLT example with which you are generating the queue entry?

The transformation step result from trace log is attached. The end user data was changed and message body truncated. The message body is HTML page.

The transformation looks fine. I have just finished a similar workflow also using the WorkQueueService Add method and it runs without problems.

Do you see the results in the flash client workqueue or in the db? If it is a new workqueue have you modeled and scripted it correctly?
