My item model and texture for a weapon I made from blockbench keeps being a purple and black cube.

I have made a model and texture using blockbench which I exported as a .json file, but when I go in game it is shown as a black and purple cube. I have tried everything that is on the https://mcreator.net/wiki/common-blockbench-issues-mcreator page and have tried stuff on many other posts to no avail. This is where the error is in mcreator, I just don't know what it means:

(ps I am sorry if this is already answered or is on a website or something, I am new to this and may have not made the connection that it would solve my problem)
