Unclear error messages in browser console with an Embed for Organization embedded report

Hello all,

I'm running into some errors (seen in screenshot below) with my embedded report (using Embed for Organization) in a portal I'm developing using .NET 6. The embedded report is still working as intended despite the errors' the browser console is dotted with. Does anyone have an idea as to what they may refer to or what could be wrong?

If anything is unclear I'm happy to provide further explanation. Any help big or small is appreciated, thanks.
