Hi,

I have been trying to use workflow_execute.pl to execute a workflow that has ~50 steps.  I keep getting this error after running for few seconds knowing I could run the same workflow from the GUI without any issue.

****************

HTTP Error 500: Internal Server Error

500 Internal Server Error

The server has either erred or is incapable of performing

the requested operation.

And here is some error I capture in the log file>

  File "/usr/local/galaxy/galaxy-dist/lib/galaxy/tools/__init__.py", line 2126, in execute

    return self.tool_action.execute( self, trans, incoming=incoming, set_output_hid=set_output_hid, history=history, **kwargs )

  File "/usr/local/galaxy/galaxy-dist/lib/galaxy/tools/actions/__init__.py", line 362, in execute

    history.add_dataset( data, set_hid = set_output_hid )

  File "/usr/local/galaxy/galaxy-dist/lib/galaxy/web/framework/__init__.py", line 1124, in __getattr__

    if key not in self: raise AttributeError, key

AttributeError: add_dataset

Looking at the created history the first 14 steps get scheduled and executed.  But nothing else.  Meaning the rest of the steps get omitted.  This could be due to the script get crashed before it complete registering the rest of the steps of the workflow.

Does anyone has any idea what could be going on here?

Best regards.
