How to access jsreport from cross domain

rashmim00

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"
    });
    app.use(cors({origin:'*'}));
    jsreport.init()
        .then(() => {
            console.log(`JSReport instance ${process.pid} started correctly.`);
        }).catch((e) => {
            console.error(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,
Rashmi

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.
