Hi, I'm hoping you can help.
I've inherited an older project and it uses an older version of jsreport.

Right now there is no authentication on the admin interface, which we need.

So I followed the docs and added in this code, but it doesn't work:
'''authentication": {
"cookieSession": {
"secret": "R14TFfguolODckC6GKxaaAunGmioyqCJ447LvxV"
},
"admin": {
"username": "admin",
"password": "password"
},
"enabled": true
},
'''
Is there anything else anywhere else I should check to make sure the authentication kicked in?
Right now it totally ignores this code and the admin UI just loads like normal.
Any help would be appreciated.

I fixed it!
Although I don't know why what I did worked.

Turns out it was something with my English template. I made a new template and literally copied and pasted all the info from my original EN template to the my new one and changed the template ID in my app and it started working. If I change the ID back the old EN template I get those errors. So somewhere along the way something happened to that template, but it's not in the markup since I copied all that into the new template and that works fine. It must be something else somewhere in files that we don't touch.
Weird.

This is all it says:
Error occured - Error during rendering report: Unexpected end of JSON input Stak - SyntaxError: Unexpected end of JSON input at Object.parse (native) at IncomingMessage.result.on (evalmachine.<anonymous>:13:46) at emitNone (events.js:91:20) at IncomingMessage.emit (events.js:185:7) at endReadableNT (_stream_readable.js:978:12) at _combinedTickCallback (internal/process/next_tick.js:80:11) at process._tickCallback (internal/process/next_tick.js:104:9)

What's weird is that my app is bilingual. English and French use the same JSON that is sent to 2 different templates, one for EN and one for FR. When I send to the FR template it works, but when I send to the EN it gives this error. The ONLY thing that's different about the JSON being sent to both of these templates is the template var that is either set the EN's template ID or the FR template's ID.. that's it. And I've checked to make sure the EN template ID is correct, it is. The rest of the body data is exactly the same. Could there be something in the markup of a template that could cause this error?

I just tried our Dev server (my other post was for our Prod server) and I'm getting the same error there. Dev has been working fine for months.
Any hints as to where to look exactly for what might be causing this issue suddenly?

Any idea why last week I my Angular app was connecting to jsreport and generating PDFs fine, and now I check it today and when I try to render a report I get this error:
"Error during rendering report: Unexpected end of JSON input"

I haven't made any changes to it since since it last worked.

This first option worked great =)
My issue was/is that I have a PM2 server watching to make sure jsreport doesn't go down, but when I tell pm2 to start my server.js file, everything starts up but it doesn't seem to pick my my prod.config.json, so it was running on the wrong port and lost the rest of my config options. It didn't seem to be picking up either of configs.. because both my dev and prod config files define my port as 4201.. but it started on the default port of 5488.

Is there a way to define in server.js which config it should use? Either dev.config.json or prod.config.json?

Thanks for your help so far. I really appreciate it.

So running either node server.js or npm start both work and do the same thing... without my customized port. I do have a prod.config.json defined, so if I run npm start --production then it runs with the correct port.

Running npm run jsreport gives me an error:

I'm assuming given what we've assessed so far this is not surprising?

Thanks for the clarification, that clears a couple things up a bit.
I'm following the files on Dev as close as possible trying to keep Prod as close to Dev (which works fine) as possible, so I'm following its config format and only deviating when something doesn't work as expected.

I'm glad that running node server.js works for me, but do you have any ideas as to why trying to run the scripts in the package.json file don't work? Is this the same probable that we've been trying to debug or a different issue? I guess this means I can't write any of my own scripts there either then if it can't seem to find them.
