Table chart: Error appears when trying to import from JSON

[rodica-andronache]

I've tried the import from JSON using multiple sources, and I was not able to actually create a chart. All the time I get an error that can be visible in this video

As a source, I've used http://dummy.restapiexample.com/api/v1/employees

@rodica-andronache I believe this happens only for table charts. In other charts JSON feed works as expected.

PR #614

@contactashish13 I've tried this again with the #614, and now is working well to create the chart.
The issue is when you are trying to create a post with that chart, in the Gutenberg editor. The same error appears.
Using the classic editor, displaying the chart is working well.
