newAppConfig.getContentConfig().getReleaseVersion() is null

It's weird, since if server gave 500 - app should have failed to download config. Maybe it did download the chcp.json file, but it has no release preference?

thinkphp error Message cause bug

In the following manner to solve the problem of collapse

UpdateLoaderWorker

    // download new application config
    ApplicationConfig newAppConfig = downloadApplicationConfig();
    if (newAppConfig == null) {
        setErrorResult(ChcpError.FAILED_TO_DOWNLOAD_APPLICATION_CONFIG, null);
        return;
    }

    String newVersion = newAppConfig.getContentConfig().getReleaseVersion();
    if (newVersion == null) {
        setErrorResult(ChcpError.FAILED_TO_DOWNLOAD_APPLICATION_CONFIG, null);
        return;
    }

Agree, wanted to add similar code. Just want to make sure, that it's not a problem in the chcp.json file, that is placed on the server.
