[Solved] Tommy - Nodesjs + Puppeteer - Error "Incomplete response received from application"

[paladino]

Hi there!

 

I've done a test on tommy using nodejs + puppeteer node module to test if I can run my app there. The app.js just contains the basic code to start de webserver (which works) and launch a puppeteer instance. 

When I open the url, I receive this message "Incomplete response received from application". If I remove the puppeteer launch code, It works and start the webserver then I can see my test output.

 

I've uploaded the linux node_modules package to my folder that contains all modules I use in my app. These modules I've downloaded from linux mint distribution via npm. Since I'm not a linux user and my knownledge about linux env is very limited, I haven't' sure if the modules are correct to run on Tommy server... 

 

Please, could you help me to see what's going on?

 

Thanks!

What is the url?

Hi,

 

The url is: http://rpaladino.heliohost.org/fii

 

The node app just try to launch the puppeteer module and this error pop up. Without the puppeter launch, it works.

 

Thanks!

Thanks for the info.

.

I give some google and found that it could be permission to the chromium folder. I managed to change it to 777, now the error appears after 1 minute. I believe that's other problem now...

 

One more thing: could you verify if theses libs are installed?

Finally, please, could you check the logs again?

Xorg is a desktop, and you also listed a screensaver. Tommy is a headless server so he has no need of desktops or screensavers.

[paladino]

I understand. So that's why puppeteer will not work.

 

Thanks!
