Fireworks WebGui not launching

Eric_Sivonxay · April 25, 2017, 8:50pm

Hello,

I’m having issues launching the lpad webgui. It was working previously, but now i’m getting the following error:

I am able to run lpad get_wflows command for all states except for COMPLETED workflows, where it throws this list index out of range error. Does anyone have any suggestions to fix this error?

Thanks,

Hi Eric

Can you tell me:

i) Which update to the FireWorks code seems to break the feature (you said it was working before, but no longer - does reverting to an older version of FWS fix it)?

ii) What exactly is the query you are using?

iii) If you are comfortable with modifying the source, you can add a quick debug print above the offending line (line 132 in app.py) that prints out what the variable “item” looks like. Let me know if you are able to do that and what the result is.

Best

Hi Anubhav,

I haven’t updated Fireworks. I’m new to fireworks, so this was probably the first time a workflow was marked as completed. I think the issue stems from this.
i get errors when I use

lpad webgui
lpad get_wflows -s COMPLETED
but no errors when I use any of the following commands

lpad get_wflows -s {RUNNING, PAUSE, READY, WAITING, DEFUSED}

printing item gives the following output:

{‘metadata’: {}, ‘name’: ‘Li64 Si64_longruns’, ‘parent_links’: {}, ‘fw_states’: {}, ‘links’: {}, ‘state’: ‘COMPLETED’, ‘updated_on’: datetime.datetime(2017, 4, 25, 17, 22, 49, 245000), ‘_id’: ObjectId(‘58ff85e937cea8c8d89240b1’), ‘created_on’: datetime.datetime(2017, 4, 25, 17, 22, 49, 245000), ‘nodes’: []}

Thanks,

Eric

To anyone following this thread: Eric and I followed up. We think Eric might have had some dynamic workflows created that were empty, i.e., had zero Fireworks inside. This was unintentional on his part and indeed should not even have been possible with FireWorks. I pushed an update to FireWorks to not allow the creation of empty workflows which should prevent this problem from happening again.
