Error when running template after moving codebase to new server

Lukerayn3r

Hi i am receiving the following error when I run a report on my server

TypeError: input.on is not a function
    at new Interface (readline.js:206:11)
    at Object.createInterface (readline.js:74:10)
    at Promise (/var/www/html/jsreportapp/node_modules/puppeteer/lib/Launcher.js:327:25)
    at new Promise (<anonymous>)
    at waitForWSEndpoint (/var/www/html/jsreportapp/node_modules/puppeteer/lib/Launcher.js:326:10)
    at Launcher.launch (/var/www/html/jsreportapp/node_modules/puppeteer/lib/Launcher.js:170:41)

I recently moved the code from one server to another and now I cant seem to run any reports.

These are the steps I took to transfer the files to the new server

Copied jsreportapp dir to new server
Im using apache virtual hosts so I setup a new virtual host
I then installed pm2 onto my server
I then ran the following command npm install jsreport-cli -g to install jsreport
I then used this command pm2 start server.js to run the server

Is there anything I may have missed which needs to be ran in order to get the server working?

I also get the following error sometime The server is temporarily unable to service your request due to maintenance downtime or capacity problems. Please try again later.

When I view my chrome debug network tab I keep seeing the following requests every few seconds https://jsreport.intelli-sense.co.uk/socket.io/?EIO=3&transport=polling&t=NGgvLdW&sid=wSoCkXCAA157kWOVAAAA and the response is

Service Unavailable

Did you copy between the same os/version/architecture?

This error is related to server-side chrome launch. Searching the internet I see here mentioned this can have something to do with not enough resources to launch chrome. Does your VM have enough resources?

Lukerayn3r

Yes the servers are both hosted by AWS and they are using a t2.medium so the resource should be the exact same. I find it odd that sometimes the erros I receive are different which has made it hard for me to resolve.

I stopped my pm2 service and tried starting the node server jsreport start and after it tries to load I then get the same error in my console which means I cant start jsreport either

Maybe try to remove node_modules and run npm install again. Maybe something went wrong with the copy of the chrome binary...

Also please check you have the same node.js version on both.
