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. -Dannon On Feb 21, 2012, at 6:22 PM, thondeb...@me.com wrote: > Hi, > > I tried to run a workflow with the API, but get an Error 500 when I try to > run the WF...The paster.log shows the following error... > > $ workflow_execute.py 92cc01ed93dc0f0fc91e3ded35497c0a > http://srp106:8080/api/workflows ebfb8f50c6abde6d 'TEST the API' > '1=ldda=7c5ebce002fc9d5c' > > > Paster.log > galaxy.web.framework ERROR 2012-02-21 14:36:33,067 Uncaught exception in > exposed API method: > Traceback (most recent call last): > File > "/home/tdeboer/code/galaxy-central/lib/galaxy/web/framework/__init__.py", > line 145, in decorator > return simplejson.dumps( func( self, trans, *args, **kwargs ), indent=4, > sort_keys=True ) > File "/home/tdeboer/code/galaxy-central/lib/galaxy/web/api/workflows.py", > line 123, in create > hda = ldda.to_history_dataset_association(history, > add_to_history=add_to_history) > AttributeError: 'NoneType' object has no attribute > 'to_history_dataset_association' > 172.16.108.6 - - [21/Feb/2012:14:36:32 -0700] "POST > /api/workflows?key=92cc01ed93dc0f0fc91e3ded35497c0a HTTP/1.1" 500 - "-" > "Python-urllib/2.6" > > > Any ideas? > > Also...I had a hard time finding out what I should use for the dataset source > parameter "src" in "step=src=dataset_id" and just tried ldda, but would hope > there is a little info on what this hda and ldda is? > > Thanks, > > Thon > ___________________________________________________________ > Please keep all replies on the list by using "reply all" > in your mail client.
