TypeError: Converting circular exporting extension to pdf

davequinn — Fri, 20 Jan 2017 10:29:32 GMT

Hi,

I'm getting the following javascript error when i select Export to PDF on my d3 extension:

require.js:44 TypeError: Converting circular structure to JSON

at JSON.stringify (<anonymous>)

at Object.s [as formatSnapshotForRendering] (:4848/resources/assets/client/client.js??

I am following the instructions on help.qlik.com:

Properties includes this:

support: {

snapshot: true,

export: true,

exportData: true

and my Paint method ends with

return qlik.Promise.resolve();

Can anyone help?

Thanks,

Dave

So what happens during both snapshot and exporting is that we take the current layout you have save it away as a snapshot or send it to the printing service.

Can you share a bit more code, such as the intialProperties.

Are you importing any unsupported internal Qlik modules?
