How to access jsreport from cross domain

  • Hi,
    Sorry if similar question has already been asked. I looked before posting and couldn't find any posting. My jsreport is running on port 3000 and my other application is on port 2000. I am trying to call jsreport from http://localhost:2000 and am setting up cors to allow origin

    /// define the jsreport middleware
        let jsreport = require('jsreport')({
            express: { app :reportingApp, server: server },
            appPath: "/reporting"
            .then(() => {
                console.log(`JSReport instance ${} started correctly.`);
            }).catch((e) => {

    but still I get this error
    Error: Error during processing request: http://localhost:3000/reporting/api/report details: Error during rendering report: Cannot use 'in' operator to search for '$ref' in Project Id TypeError: Cannot use 'in' operator to search for '$ref' in Project Id
    at recurse (C:\ifolder\iroot\jsReport\node_modules\jsreport\node_modules\jsreport-core\lib\render\resolveReferences.js:19:26)
    at module.exports (C:\ifolder\iroot\jsReport\node_modules\jsreport\node_modules\jsreport-core\lib\render\resolveReferences.js:52:5)

    Is the error related to cross domain reference or its something else?

    Thank you,

  • Hi, this error is not related to the cors.
    jsreport fails here when parsing your input data.
    We are parsing the input data in a way that we resolve references and circular structures in the input. This allows a smaller data transfer and more comfortable way to work with the data after wards. At this place it crashes. You likely have some invalid $ref props in your input json.

    Check this for some info


  • Thank you Jan. My input data was bad.
