regression: inversify 6 no longer allows binding null values

[simhnna]

Used to work in inversify 5

import { Container } from "inversify";

const container = new Container();
const s = Symbol('foo');
container.bind(s).toConstantValue(null);


console.log(container.get(s));

Produces:

/project/node_modules/inversify/lib/utils/binding_utils.js:62
        throw new Error(ERROR_MSGS.INVALID_BINDING_TYPE + " " + serviceIdentifierAsString);
              ^

Error: Invalid binding type: Symbol(foo)

Have you found a solution for this?

[simhnna]

You can wrap primitives { value: null }

It's currently no longer a high priority for my projects. If I have time I might try creating a merge request that allows binding null values but understanding the code of inversofy isn't very easy...

Added to milestone 6.0.3, we will aim to resolve this regression as a priority. cc @PodaruDragos
