Message that Some Features May Not Work pops up, but document loads

Hello -

On initial load of the document, which is embedded into our application, we get a brief warning message that Some Features May Not Work. The error comes up for a few seconds and then goes away, and the document loads successfully after that. Our documents are loaded through a React viewer that takes some parameters, sends it to our server which creates and sends back a redis key. The redis key is used to call a URL that loads the document, on which step we are getting the error message.

Is there a way to supress this warning or something else going on?
