Angular 8x: Cannot read property 'pvtData' of undefined (UrlAdaptor)

[Viktor]

Hi,
After upgrading to Angular 8 from 7 the grid or more specifically UrlAdaptor stopped working (see screenshots below).
btw.
i have already tried to switch  from es2015 to es5 and it did not help.

any idea how to fix this problem?

thanks

viktor

class SongsUrlAdaptor extends UrlAdaptor {

    constructor() {
        super();
    }

    processResponse(): DataResult {
        const original = super.processResponse.apply(this, arguments);
        const songs = original.result.map((item) => { return new Song(item); });
        return {
            result: songs,
            count: original.count
        };
    }
}

Hi Viktor, 

Thanks for contacting Syncfusion support. 

From your query we suspect that some duplicate package might be installed in “@syncfusion” folder of node_modules while updating. This may occur due to version mismatch of packages. So we suggest you to delete the “@syncfusion” folder and “package.lock.json” file from your application and follow the steps provided in the below documentation for update the packages. 

Documentation: https://ej2.syncfusion.com/angular/documentation/common/how-to/update-npm-package/ 

Please get back to us if you need further assistance.
