What update are you talking about? What version of SkyWeather2?
We did fix some lightning page stuff in V027D which is due out at the end of next week.
Does the lightning page show up first and then the update fails?

I've seen this error on a few releases of SkyWeather2's dash. It normally squawks when you click on the syslog tab on the nav bar. Since it doesn't take down the app and I'm lazy I have been ignoring it.
I also found an indent error (should have been indented) in dash_app.py in a nested if then else which causes the object fig to be returned when it is not defined (it is in the nested if statement but it is not defined because the condition is not met). I'll find the lines and version for you when I can get at the code.

027 Is going out on Thursday. I'd really like to have this fixed for that. Doxidad? Your fix would be good too.

trericon,
What did you to do to get this error? Switch from lightning to log page? That's my suspicion.

Here's where the indent is incorrect in index.py that returns the error about fig not being defined. line 181+ 182 need indented one more level to be blocked with the previous if statement - it is now blocked with the main if statement and if the next if is not met will return fig without being defined.
169 def logpageupdate(n_intervals, id, value):
170
171 #if (True): # 1 minutes -10 second timer
172 if ((n_intervals % (1*6)) == 0): # 1 minutes -10 second timer
173 #print ("---->inputs:",dash.callback_context.inputs)
174 #print(">log_page table Update started",id['index'])
175 #print("LG-n_intervals=", n_intervals)
176 if (id['index'] == "systemlog"):
177 data = log_page.fetchSystemLog()
178 fig = log_page.buildTableFig(data,"System Log")
179
180
181 #print("<log_page table Update complete",id['index'])
182 return fig
183 else:
184 raise PreventUpdate
I'm not sure where the problem is in with the "KeyError: 'systemlog' error. I find it happens when logs are selected and it happens every 10 seconds so it has something to do with the refresh of the screen.

doxidad,
Thanks. I've fixed the errant indent in V027.
Regarding the lighting index. I'm looking. Something is updating that shouldn't.
