Tcp send failing as of last night - working before

Developer Programs Writing Edge Drivers

Suddenly since last night, I am getting this error - when sending a tcp message on LAN…

tcp:connect(self.ip, self.port)
tcp:send(command)

[string "cosock/socket/internals.lua"]:54: attempt to call a nil value (field '?')

The same code was working perfectly for the last 2-3 months or so - until last night (maybe a new version of hub firmware was deployed?)

Funnily enough, simply redeploying the app fixed the problem. Restarting the hub did NOT solve the problem. Maybe something about how it was deployed changed due to a firmware update?

46.10 was pushed to hubs earlier this week. I’d check the change log for it to see if it may have caused the issue.
