One more question...
How do I pass a string value to one of the workflow input steps?
Is there an equivalent of ldda and hda, maybe "str"..
So 38=str="Some value"
Where could I find a list of the expected dataset sources?
Thanks

Hi Thon,
You have the right idea about what's going wrong here. Galaxy is trying to pull up a library dataset with the ID you specify, but it doesn't exist.
In this context, src refers to the 'type' of dataset input id, more specifically whether it's from a history or library. 'hda' indicates that the dataset is from a history, and 'ldda' is what you'll most likely use in the case of a library dataset. If you browse the history and library API functionality, you'll see other methods for explicitly grabbing these ids.
My hunch is that you have an id from a history and that you should swap ldda to hda and give it another shot. Definitely let me know if you run into more issues, though, and I'll help figure out what's going on.
