Export picasso visualization as image or pdf
hill84 opened this issue ยท 1 comments
Hi everybody! ๐
I want to export a custom chart visualization I created with Picasso.js in a Qlik sense mashup (created with React.js) as Pdf or image. I've been able to set a function to export the same chart as data (.xlsx), but when I try to export it as image or Pdf I receive an "Internal Server Error" (on server) or a "Blocked by CORS warning" (on localhost). The same functions work well with embedded Sense visualizations.
I am using the exportPdf and exportImg methods of the Visualization API.
My issue seams the same as this topic in the Qlik Community Forum.
What am I doing wrong? ๐ญ
My function:
qApp.visualization.get(objectId).then(qViz => {
qViz.exportPdf(settings).then(res => {
this.downloadURI(res, fileName);
}).catch(err => console.log(err)); // ERROR
}).catch(err => console.log(err));
The server error:
POST https://40.113.14.238/printing/export/object/pdf?requestId=957dc6b8-3e3b-4fdd-94c8-ae3dddc87411 500
The local error:
Access to XMLHttpRequest at 'http://localhost:9073/printing/export/object/image?requestId=61981b8a-d45b-4dfb-a622-e1f19dd65027' from origin 'http://localhost:3000' has been blocked by CORS policy: Response to preflight request doesn't pass access control check: The value of the 'Access-Control-Allow-Origin' header in the response must not be the wildcard '*' when the request's credentials mode is 'include'. The credentials mode of requests initiated by the XMLHttpRequest is controlled by the withCredentials attribute.
My mashup config:
"DESKTOP": {
host: 'localhost',
secure: false,
port: 4848,
prefix: '',
appId: 'appname.qvf'
}
Hi @hill84,
Exporting and Visualization API in Qlik is not managed by picasso, you might wanna try https://community.qlik.com/t5/Qlik-Sense-Integration/bd-p/qlik-sense-integration-extension-api
