Hi Bhanu,

Currently, custom visualizations and their dependencies (like utils.js and d3v4.js) need to be written in ES5 to work with PhantomJS for downloading and scheduling. Code can easily be converted with a tool like Babel ( Looker will be migrating to a different rendering engine in the near future which should alleviate this requirement.

Looking at the error it feels like that is what’s happening in your case. Custom visualisations is still a very beta feature. We provide examples that can be found Here but somethings might not work as expected still.

Should you have more questions feel free to pop back on chat with us.



Hi Sasha,

thanks for your reply, so you want me to take the until.js and d3v4.js files and convert it to ES5 and place it in the same plugins/common folder with same names?

could you please briefly explain the steps how to fix this issue?

we have so many maps in our reports and after the upgrade nothing is working out.
