Ok, rookie error. Thanks Jan.

Can I please get some help to find the jsreport.config.json file?

This is what I see in studio:

The js file (which returns the Unable to find or read error) is in the same folder as the css file (which works fine)

I am unable to do anything in the permissions section for this js file in the studio. What are the correct permissions and where do I add them? Is it in the main config file, the config file for the report template or the config file for the js file?

Also, if I reference css files from the same assets folder it works both on my local and on the server

On my local I am able to reference js files that are in my assets folder like so:

 {#asset quadrantConfig.js @encoding=utf8}

On the deployed server if I attempt to reference an asset in the same way (same file same structure same everything) I get this error:

Can I get some clarification as to how to make this work?
