[geni-users] Issue with the stitching service

[Aditi Ghag]

Hi,

I am trying to use the stitching service, but I am getting this error-

ERROR <Fault -500: "Unexpected error executing code for particular method, detected by Xmlrpc-c method registry code.  Method did not fail; rather, it did not complete at all.  Xmlrpc-c user's xmlrpc_c::method object's 'execute method' failed to set the RPC result value.">

09:09:20 ERROR    stitcher: Exception from slice computation service: <Fault -500: "Unexpected error executing code for particular method, detected by Xmlrpc-c method registry code.  Method did not fail; rather, it did not complete at all.  Xmlrpc-c user's xmlrpc_c::method object's 'execute method' failed to set the RPC result value.">

SCS gave error: <Fault -500: "Unexpected error executing code for particular method, detected by Xmlrpc-c method registry code.  Method did not fail; rather, it did not complete at all.  Xmlrpc-c user's xmlrpc_c::method object's 'execute method' failed to set the RPC result value.">

Please let me know how to fix this error.

Thanks,

Aditi

Hello Aditi,

The problem with the Stitching Computation Service has been resolved,
please try your experiment again.

Thanks,
Luisa

Thanks Luisa.

I tried it again, and this time I am getting some different error. 

No path found in rspec with id = '##all_paths_merged##'

What could be the issue here?

That's a bug in the SCS (new code that isn't quite ready).

In the meantime, you can work around the issue if you are willing to edit Omni code.

Edit src/omnilib/stitch/workflow.py
Go to line 66, which says
                raise StitchingError(msg)
 Insert as the first character of that line, a # (comment character),
and then insert a new line 67 that says "continue", indented to the same level as the word "msg" on line 65. So the new section looks like:

        for link_id in workflow:
            path = rspec.find_path(link_id)
            if not path:
                msg = "No path found in rspec with id = %r" % (link_id)
#                raise StitchingError(msg)
                continue
            deps = workflow[link_id][self.DEPENDENCIES_KEY]

And try again.

Thanks for your persistence,
Aaron

Hum not sure?!?
I have not seen this one before, but if you send me your
RSpec, I can take a look and hopefully explain it for you.

Please ignore my message, I had not seen Aaron's reply.
Sorry,
Luisa

[Aditi Ghag]

Thanks Aaron. 

Would you have instructions for Mac? I'll give it a try if it works. 

Aditi

[Aaron Helsinger]

The issue with the SCS is fixed now. No need for the workaround.

Aaron

[Aditi Ghag]

Yup, I am not seeing any of the errors below. Thanks for the update Aaron.
