WpdExtendlet$WpdLoader.getRealPath() is to get real path of a wpd file request like /web/_zv2021081016/js/zul.utl.wpd. The related code is:

final int j = path.lastIndexOf(".wpd"); 
return path.substring(0, j).replace('.', '/') + "/zk" + path.substring(j);

If the path is to request a WPD, then j should be larger than -1. Normally, getting a wpd file should not fail.

Please open a browser developer tool > Network tab to check which request failed. Because the exception should cause the request to fail like: image description
