AssertionError: View function mapping is overwriting an existing endpoint function whilre creating DB for FLASK project

As I am trying to create the DB for this online tutorial I am getting the error below when I run the following command in python environment

from api import db,create_app
db.create_all(app=create_app())

The error I am getting is as follows:

  File "C:\JS_Class\tests\ng-blog\api\__init__.py", line 21, in create_app
app.register_blueprint(blogs)
  AssertionError: View function mapping is overwriting an existing endpoint function: blogs.wrapper

Can Someone push me into the right direction for this as I am stuck and I don't know where to look for more answers...

Problem seems to be with the routes inside api/Blog/blog_routes.py that are decorated with @jwt_required. For example:

@blogs.route("/delete_blog/<int:id>", methods=["DELETE"])
@jwt_required
def delete_blog(id):
    blog = Blog.query.filter_by(id=id).first()
    db.session.delete(blog)
    db.session.commit()

    return jsonify("Blog was deleted"), 200

From looking at the documentation and trying your code out it seems that it should be @jwt_required() instead of @jwt_required. So it should look more like this:

@blogs.route("/delete_blog/<int:id>", methods=["DELETE"])
@jwt_required()
def delete_blog(id):
    blog = Blog.query.filter_by(id=id).first()
    db.session.delete(blog)
    db.session.commit()

    return jsonify("Blog was deleted"), 200

Change this for all instances where you use @jwt_required in that file.
