Error loading providers

#1

Probably this is a silly question since I’m starting with toolkit now, but it’s driving me crazy. I’m trying to display a visual (a simple bars), but I keep getting this error:

A provider is required

I’m using an Elasticsearch server in my local and I included the cft-elasticsearch-provider.min.js library in my app too. So honestly don’t know what is going on. This is the code for my visualization:

cf.provider('Elasticsearch')
    .source('prtz_reports')
    .groupby(iff_source)
    .metrics(delegated)
    .graph('Bars')
    .execute()
```
Error: A provider is required

Your query is correct except for one thing which btw is not related with your issue: You are missing the .element('div-id') so you can actually render a Bars within that div-id element.

Now, regarding to the actual issue, did you register your provider before executing your visuals? I mean this:

cf.setProviders(providers)

Remember that providers should be an array of JSON configs.

Sorry for the late response, I find out what was happening. Yes of course I was using the cf.setProviders() with the configuration, but my configuration was using as the name of the provider: “elasticsearch” instead of “Elasticsearch” which is the one that I’m using in the visualization. As soon as I changed them, it worked!

It happened to me in the past as well and several times, and it gets a little more complicated when you have a lot of visualizations. So, what I usually do is to declare a variable with the name of the provider and the name of the source that I’ll use across all of my visualizations, so that way I avoid miss-typing names.
