custom visual is allways not loading in power bi javascript api

[mikihiir]

I have troubles sometimes loading my reportis with power bi javascript api.

Sometimes they do open.

WindowsPostMessageProxy message shoud allway be object type, sometimes it is a string. there lies my problem. Why is it string?

And when it is tring i get this warning and report is not loaded.

 Any ideas ?

@mikihiir,

Based on my research, you could try to insert a code snippet to parse the JSON string.

if (typeof message === "string") {
    console.log("parse a JSON string");
    // message = eval('(' + message + ')');
    message = JSON.parse(message);
}
