Hi there

 

 

I get after a few days always this error on  a scene

[DEBUG] 18:48:30: 2021-04-08 18:48:30.432433 [ error] API: Host not found (authoritative)
[DEBUG] 18:48:35: 2021-04-08 18:48:35.437767 [ error] API: Host not found (authoritative)
[DEBUG] 18:48:35: 2021-04-08 18:48:35.439204 [ fatal] Unknown exception: /opt/fibaro/scenes/414.lua:45: attempt to compare number with nil

 

 

Is this a bug , here is my scene , was working before without problem ,  is there a possibility to fix it

Thanks for the reply

 

So if I understand correctly I should load the global variable into a local one ?

 

But is this a bug or working as designed I don't really understand why this happens

And in the while loop I added already the variable in local

Well AFAIK in my house it rarely happens because my internet (both WAN and LAN) are very, very reliable. The issue gets posted by users who have full or partial loss of the "internet" side of their router. I cannot confirm or deny the issue.

 

To me it seems like increasing the reliability of your internet would give best and fastest results...

 

On the other hand, for long running scenes or Virtual Devices or Quick Apps on HC3 to get the most reliable and stable performance it is best to add error checking and handling. I mean "error" in a broad way like API returning "nil" and json decode crashing due to invalid data you get from external servers and so on.

 

If you only have a few scenes or CDs that are affected by then try "pcall"

This won't *fix* the problem but might allow you to "keep stuff running".

Hmm strange I have a very reliable internet conenction , Fibaro HC2 is connected Directly to my Unifi Dream Machine Pro.

Fiber Internet connection

Here's what I would do. If that Unifi has logs (about connect/disconnect events for example) or keeps stats (like interface events and errors) - maybe you can correlate with those Lua errors. If that does not help, contact [email protected] so they can have a look at the internal log files of your HC2. You might have found a new issue but I doubt it because this 4.610 has been around for a while now.
