Extensions timeout

[Simon Ryf]

Sorry I’m tiered – it isn’t about extensions but general device timeout…

Dan and Zaid – do you know that you’re still having a “bug” when using Node >=8.x on that?

https://nodejs.org/api/http.html#http_server_keepalivetimeout

you need to fix that in server.js I can give you the code I’ve added for that.
I’m not really a Node dev and therefore I didn’t yet made a pull request…

Cheers
Simon

You can increase the extension timeout by adding "EXT_TIMEOUT": 30000, to the genieacs/config/config.json file. Timeout is in milliseconds.

Hello Genieacs users,

my extensions sometimes results in timeout without a reason giving a NodeJS
error in the log:

My extension is called from Provision script:

And the extension:
