[SOLVED]Update broke some QA's - error: "Host not found (authoritative)"

[Momos 103]

As the title says, the update broke some of my QA's giving the error message:  error: "Host not found (authoritative)"

These QA's were running just fine for at least 6 months. 

Even more, some other QA's which are basically the same (all make a http call to read some json from other devices) still work fine.

 

Any ideas please ?

 

Cheers

Hi. Are you able to extract piece of LUA code that cause that error?
I have just updated and just checked several of my QuickApps that call different http services, from local devices and cloud, so opened and with different authentication protocols, and all works fine.

Ok, so i figured it out...

In some QA's the update introduced an extra space in a variable....

 

It looks ok in the variables QA screen:

But the Path have an extra blank space that came out of nowhere 

 

 

Obviously i did not put it there as those QA's used to work for months wihtout me touching them.

 

 

Cheers.

Is it possibile that those spaces were there always? We changed a bit in the system in this GA and maybe before the update those was ignored.

 

There was no migration od any data related to variables in this version, probably never.

There is no way that those spaces were there as they would have shown up in composing the called URL and hence failed to get the answer.  I think..  would have been strange that they were there and still get ignored when composing the URL.

 

  local http = net.HTTPClient({timeout=3000}) 

  local ipaddress = self:getVariable("IPaddress") 

  local path = self:getVariable("Path")

  local interval = tonumber(self:getVariable("Interval")) 

  local UserID = tonumber(self:getVariable("UserID"))

  local url = "http://"..ipaddress..path

  self:debug("Url: "..url)

I am getting the same errors.

I am also having issues  with http calls, that where working fine for months.
But I can't find any added spaces anywhere in the variables.
"Operation cancelled" is the error I am seeing.

Edit: Increasing timeout to 10s solved the issue, 5s wasn't enough somehow anymore.
