Header Warnings flooding console

I’ve got two warnings that show up together every 10 seconds in my console when media is playing.

If anyone can direct me to the appropriate headers to change/add I’d appreciate it.

Did not move header "accept" to query string. This can result in an unnecessary OPTIONS preflight request.    883-883-f1b1427bce9454e51024-plex-4.87.2.25887-d04a1ad.js:2

An entity does not exist with the type "servers" and id "undefined"    883-883-f1b1427bce9454e51024-plex-4.87.2.25887-d04a1ad.js:2

Use the hosted web app instead and see if the error persists.

Same outcome.
