Problem downloading excel Pivot when I add enginePopulated

Question

I have a problem, when I add enginePopulated to my pivot to perform certain functions, the function to download the excel doesn't work and throws this error.

I tried to replicate this error on stackblitz but it works fine.

https://stackblitz.com/edit/ed7dya-kv2z4l?file=index.js

The only difference is that I am handling an eval to transform the pivot configuration from text to javascript code.

for example:

data = eval(elem_unimeds.gridOptions.enginePopulated);
eval("elem_unimeds.gridOptions.enginePopulated=" + this.fun);
//Inicializa el grid (Detalle)
var pivotObj = new ej.pivotview.PivotView(elem_unimeds.gridOptions);
pivotObj.appendTo("#" + elem_unimeds.grid_id);

I hope you can help me with some suggestions. Thanks in advance.

Hi louis, 

Could you please tell us why you convert the text to JavaScript using the eval() function, which results in the reported problem on your end? Could you also please provide us your sample with the reported problem replicates in a runnable state? This would allow us to investigate the reported problem on our end and respond as quickly as possible.

This is because part of the pivot configuration, such as the data from the datasource, I do from a backend (in this case Django), and I bring it as text to the frontend.

Since most of the html code can be handled by views(view.py) to render on the frontend.
