how to fix an entity error (specific error)

so, a lot of people have issues with errors, and so did i when making a mod called PARASITES, my minecraft wouldn't launch because of an error, this error is very simple to fix but i have no idea if anyone already talked about it, and i don't think so. If you have an error in an entity model (or block model i don't know if it is possible tho), check in blockbench if one of the names of your entity starts with a number, then you just have to remove this number and voilà, it's fixed (if you have this issue), i hope this can help at least some people
