I have encountered the problem when npm start

root@isc-kea-primary:~/src/kea-anterius#npm start

[email protected] start /home/tgdd/src/kea-anterius node ./bin/www

Thank you for raising this concern @mrhieu1311.

This error is likely to be caused by a delay in response from the Kea CA API. I wasn't able to reproduce this exact situation in my setup, nevertheless, will add a fix in the API function to process such errors.

[raybellis]

Jerin, a possible cause is this in api_service.js:

            res.on('data', function (body) {
                // console.log('BODY: ' + body);
                response_data = JSON.parse(body)[0];
            });

It's perfectly possible that the body may be split across multiple .on('data') events, so the normal paradigm here is to simply accumulate the body content into a variable in the enclosing scope, and then perform the parsing in the .on('end') callback.

[raybellis]

BTW, in related code at the point of the original reported error, this .then() callback is a "no-op":

.then(function (sapi_data) {
      return sapi_data;
});

[mrhieu1311]

BTW, in related code at the point of the original reported error, this .then() callback is a "no-op":

.then(function (sapi_data) {
      return sapi_data;
});

Hi raybellis How can i resolve this issue

[raybellis]

For the sapi_data function just omit the whole .then block completely.

[raybellis]

For the body it's something like:

var body = '';
res.on('data', function (data) {
            body += data;
});

res.on('end', function(data) {
    body += data;
    response_data = JSON.parse(body)[0];
    ....
});

[mrhieu1311]

For the body it's something like:

var body = '';
res.on('data', function (data) {
            body += data;
});

res.on('end', function(data) {
    body += data;
    response_data = JSON.parse(body)[0];
    ....
});

I comment all the line below in /lib/api_service.js and can " npm start" successfull // var response_data; // res.on('data', function (body) { // console.log('BODY: ' + body); // response_data = JSON.parse(body)[0]; // });

but when i access to web gui : localhost:3000 it exports new issue: Cannot read property 'shared-networks' of undefined

Hey @raybellis, just gave you write permission. This project is running on a skeleton crew, so not sure whether we can count on any review procedures. There aren't any defined anyway.

Feel free to commit your fix directly.

And thanks a lot for the patch!

[raybellis]

I put the patch here rather than committing direct because it's not fully tested. With it in place I can access the Anterius server, but I don't have a Kea server running for it to talk to so I get no useful content out of it.

I guess I could fork and send a PR for someone else to test, though :)

I'm not a programmer. follow your code. but still got error Error 1: TypeError: Cannot read property '0' of undefined at /home/tgdd/src/kea-anterius/app.js:249:135

[raybellis]

Try adding console.log(body) as the first line of the try block so we can see exactly what it is that the server returned.

[raybellis]

There's two separate JSON blobs appearing there - please add an extra line e.g. console.log("body dump") before the current console.log() line so we can see where each one starts.

Curiously, I can actually read both those blobs separately, so I wonder if there's a third "empty" blob that's not appearing in the console output that's actually causing the error.

[informatik-bks]

I have the same issue

[TaggerTie]

Sadly i have to report that i have the same issue.

The KEA Backend is runnig fine, but when i start the NPM i've got the same error. I've added also the latest code changes but the error is still remaining.

I am using KEA 1.4.0-p1 (DHCP4 only) with local lease memfile and several subnets.

[TaggerTie]

Does nobody have an idea?

[TaggerTie]

When i activate the outcommented line:

console.log(server,global.kea_server.server_config[global.kea_server.svr_tag], global.kea_server.sn_tag, global.kea_server.addr_tag); i've got the error message:

[Anthrino]

Hi @TaggerTie , sorry for the delay in response. Could you please pull the latest version of the repo and rerun the application. I have pushed a couple of patches attempting to fix this issue, please report if you are facing the same errors.

[TaggerTie]

Hi Anthrino, thanks for your answer. Is there any change in the source code after 19th Oktober 2018? Because i did my installation and the gitclone in the middle of November 2018 so i guess i have the latest repo.

i did a "git pull" today, And as i guess i am "Already up-todate"

the App crashes again at line 258

Error 1: TypeError: Cannot read property '0' of undefined at /home/it/kea-anterius/app.js:258:135

[TaggerTie]

:( :( :(

[Anthrino]

@TaggerTie Apologies for the delay, I had committed a patch previously to resolve this issue, unable to reproduce the error. Please allow some time to have this bug rectified.

[TaggerTie]

Thanks, please let me know if you need further information of my setup

[TaggerTie]

Does anybody else have a working KEA-Antherius Setup from which i can compare some Settings?

[satishdotpatel]

I am also getting this error and not sure what to do, i can access GUI but its not able to talk to CA I am running kea 1.6 with MySQL DB
