handle HTTP request error

[Peppe 0]

Hi All,

I'm no a professional programmer but I'm trying to make some basic code for my needs on HC2.

I wrote a code in order to get information from my SolarEdge system and based on that perform some actions like turn on the water heater, etc...

Unfortunately the SolarEdge system some times (from my test typically ones per day) responds with an error that generates a Lua fail aborting the scene.

This is the code I'm using for the HTTP request:

 

  local http = net.HTTPClient() 
  http:request("https://monitoringapi.solaredge.com/site/"..SE_CLIENT_ID.."/powerDetails?meters=FeedIn&startTime="..SEendTime.."&endTime="..SEendTime.."&api_key="..SE_API.."",{
      --options = {method = 'GET', timeout = 2000 },
    options = {method = 'GET'},
      success = process, 
    --success = function(response) fibaro:debug(response.data) end, 
      --error = error
    error = function(err) fibaro:debug("Error:"..err) end
    })

 

and this is one of the errors that I got during the day running the full code:

 

[DEBUG] 18:39:02: Error:Host not found (non-authoritative), try again later

 

Is there a way to avoid this issue and in case of an error in HTTP response just skip it and retry?

Thank you

Also with this VD?

Hi,

Yes I started with the posted code, making some changes since I have a different scope.

Anyhow also the posted code has the same issue. The serve responses with a wrong message and the scene fails.

Thank you

In the source of @D-Vine there is:

 

Please login or register to see this code.

 

 

So errors (response.status ~= 200) will be handled ok.

This could just be a temporary error from the SolarEdge cloud. That could happen, I sometimes see it in the HC3 quickapp also.

Hi thank you for the feedback!

Unfortunately I had no chance to play with the code in the last months....

Yes the piece of code processing the returned message from the SE API performs the status test, but it seems to me, that the fibaro scene is terminated before the response.status test with a fatal LUA error due to an invalid SE server response.

 

[ fatal] LUA error: Host not found (non-authoritative), try again later

 

Is there a way to keep the scene working even with a wrong response from the SE server?
