HA Floorplan initial failure

I am installing HA floorplan and added the Lovelace interface. I believe I followed all the instructions correctly, including adding the resource js in Lovelace but got the following error:

I downloaded the HA Floorplan in HACS. Is there some other step to install it?

I think you have loaded the resource correctly as the floorplan is INIT-ing Ok.

Something else is missing though. Try putting the path to your SVG in your browser and see if that loads ok

Although I have some way to go, I have got past this issue and it was a mistake I made with defining the folder levels. Schoolboy error. Thanks for the reply.
