Uncaught TypeError when loading json

[Roman Akberdin]

Failed to execute 'createObjectURL' on 'URL': No function was found that matched the signature provided.

Resource.ts:115

Just loading a regular old json file using the loader object. I use ex.Resource() to load the json with the "application/json" response type

actually I think im missing the process data handler, I guess for some reason I thought it would just work
