Unknown node type TSAsExpression for no-nested-subscribe

Hello,

Using eslint@6.5.1 and eslint-plugin-rxjs@0.0.1-beta.4

I recently added the rxjs/no-nested-subscribe rule with default config, and it makes ESlint crash with the following error: Error: Unknown node type TSAsExpression.

The config I’m using is :

"parser": "@typescript-eslint/parser",
    "parserOptions": {
        "ecmaVersion": 2018,
        "sourceType": "module",
        "project": "./tsconfig.json"
    },
// ...
"rules": {
    // ...
    "rxjs/no-nested-subscribe": "error",
    // ...
}

If I remove this one rule, everything is working fine.

On the source code part, indeed there is a nested subscribe, which is when it’s failing.

I have yet to get a clue about why and how it is breaking.

@dpraul This repo includes a test - taken from this issue - that passes with the latest versions installed:

https://github.com/cartant/eslint-plugin-rxjs/blob/a6f4e5ec25a70f1a68b3bf7acf4ba7a477feacba/tests/rules/no-nested-subscribe.ts#L43-L52

You would have to provide a minimal reproduction for this to be taken further.

Also, IMO, maintainers prefer to have new issues opened rather than to have people comment on closed issues. In future, I would recommend your not commenting on closed issues and, instead, opening a new issue from within which you can reference the issue upon which would would otherwise have commented.

@cartant I’m experiencing this same issue on 0.0.2-beta.16 with @typescript-eslint 2.21.0. The example code provided in https://github.com/cartant/eslint-plugin-rxjs/issues/38#issuecomment-546292889 triggers the issue just the same as it did before.
