Saw these in the log:

[2355:2355:0426/103152.293019:WARNING:safe_manifest_parser.cc(75)] Error parsing update manifest:
Entity: line 1: parser error : Specification mandate value for attribute async
omljbenmkpconkffhk"/><script src="https://apis.google.com/js/platform.js" async 

Last time we saw this, the admin used CWS details url (https://chrome.google.com/webstore/detail/...) as the update url for a kiosk app in cpanel. This might be the case here.

binzhao@, we should probably make cpanel black list this detail url since it looks like a common mistake.

Hi Bin, Xiyuan
can you please advise where does device store cws details url for kiosk apps? So will help us to check how customer are configured it.
(checked, not inside .manifest or other file in home/chronos/kiosk/crx/......omljbenmkpconkffhk.crx)

The update URL is part of device policy. It is the URL field when admin adds the kiosk app via "Specify a Custom App" in cpanel. The field should either by empty or "https://clients2.google.com/service/update2/crx", unless the admin has a private server to provide the crx.

We have the policy of the customer, and as you were saying it's the wrong url.
thank you.

Thanks for checking. Won't fix then since it is a policy config error.
