Cannot build web app

I am getting this error when I want to build web app using 2.5.12 and 2.6.1(Beta):

“Status: error”
“Message: Unknown error, contact support for more details”.

Hey @IAS_Valley_Secretary, We just added a new 2.6.2 (Beta) build version, could you try with that.
If that does not work, then could you add your app ID to this thread, so that we can investigate the issue.
Thanks :slight_smile:
