Plugin porting doesn't work - 6.4.4 => 7.0.0

Lino_Capalbo · May 22, 2019, 9:02am

Hi everyone,
I’m getting a strange issue porting an AngularJS plugin from kibana 6.4.4 (it works fine with this release) to kibana 7.0.0; when I try to instantiate my plugin on a Visualize I get immediately the error shown in the picture below (“Error in visualization – column is undefined”). Kibana doesn’t log anything.

import angular from 'angular';
import { uiModules } from 'ui/modules';

const module = uiModules.get('status_light_visualization/status_light_visualization', ['kibana']);
module.controller('StatusLightVisController', function ($scope, courier, $timeout) {
    function getColorFill(value) {
        if (value == "NA") {
            return $scope.vis.params.offFillColor;
        }
        if(value <= $scope.vis.params.offThreshold) {

Hmm, not exactly sure what's happening here but could you try changing your require statement to an import?

Thanks for your reply, Lukas!

I made some correction in sm_status_light_vis.js and now, strangely, the error turned in "Error: Cannot read property 'aggConfig' of undefined" (showed once the first time after selecting an index, two time if I press the Refresh button):

I solved the error just putting

defaults: [
{ type: 'count', schema: 'metric' }

in group: 'metrics'
...but..
I'don't see any drawing on Visual canvas, obviously after populating all necessary field as I did in 6.4.4 environment.

I put some console.log statements in sm_status_light_controller.js (updated on gist) but nothing is displayed in terminal where I've started kibana (yarn start from kibana dir): is it normal ?

Hi,
finally I've understand how to debug with DevTools...
I found the error :

"angular.js:14800 TypeError: Cannot read property '0' of undefined"

on this line:

    // Retrieve the id of the configured tags aggregation
    var statusAggId = $scope.vis.aggs.bySchemaName['status'][0].id;

Is it possible to know how to fix it ?

Thanks.

Hi All,
the error shown above occur only the first time, when metric is properly configured but no bucket is define and I think it's quiet normal...

If i configure a single bucket, debugging the source code i found that the following line:

var buckets = resp.aggregations[statusAggId].buckets;

shows that no key called aggregations is defined for resp object:

maybe something is changed passing from 6.4.4 to 7.0.0... but I can't figure out where the buckets object is now located under resp object.

Please, any help will be appriciated.

Thanks.
