csv / excel export fails

[BerndJM]

Both exports gives the following error (runing on Octoprint 1.2.0-dev-834):

Internal Server Error The server encountered an internal error and was unable to complete your request. Either the server is overloaded or there is an error in the application.

Even if the server is doing "nothing" so the "overloaded" isn't very possible...

what platform do you use? Win7/Linux/RaspberryPi/OctoPi?

[BerndJM]

The latest OctoPi stable image (2015-01-31-octopi-0.11.0) with Octoprint updated to the actual devel 1.2.0-dev-834

Rpi1 or 2 ? I just installed my plugin on the same version of OctoPi (but on Rpi B+) and it works fine can you provide your log file? (.octoprint/logs/octoprint.log)

Rpi2 Here the relevant part from the logfile:

2015-05-10 17:57:50,962 - octoprint - ERROR - Exception on /plugin/printhistory/export/csv [GET] Traceback (most recent call last): File "/usr/local/lib/python2.7/dist-packages/Flask-0.10.1-py2.7.egg/flask/app.py", line 1817, in wsgi_app response = self.full_dispatch_request() File "/usr/local/lib/python2.7/dist-packages/Flask-0.10.1-py2.7.egg/flask/app.py", line 1477, in full_dispatch_request rv = self.handle_user_exception(e) File "/usr/local/lib/python2.7/dist-packages/Flask-0.10.1-py2.7.egg/flask/app.py", line 1381, in handle_user_exception reraise(exc_type, exc_value, tb) File "/usr/local/lib/python2.7/dist-packages/Flask-0.10.1-py2.7.egg/flask/app.py", line 1475, in full_dispatch_request rv = self.dispatch_request() File "/usr/local/lib/python2.7/dist-packages/Flask-0.10.1-py2.7.egg/flask/app.py", line 1461, in dispatch_request return self.view_functionsrule.endpoint File "/home/pi/oprint/local/lib/python2.7/site-packages/octoprint_printhistory/init.py", line 225, in exportHistoryData writer.writerow([ historyDetails["fileName"], historyDetails["timestamp"], historyDetails["success"], historyDetails["printTime"], historyDetails["filamentLength"], historyDetails["filamentVolume"], ]); KeyError: 'printTime'

[BerndJM]

Ah ... I think I got it: there very unsuccessfull entries with no print time in the list, deleted them and the last line in the log says KeyError: 'filamentLength' Deleted also the entries with no filament usage and voila: the export works

thanks! have to fix that

[BerndJM]

Think the reason are missing lines in the history.yaml by aborted prints: 1431274784925: fileName: 798531_-SA-_clip5.gcode note: '' printTime: 54.41129803657532 success: false timestamp: 1431274784.925154

if you still have got problematic version of your history.yaml you can try with new version (0.4).
