No runnable code produced / missing unsupported syntax information

[dragmz]

I've got a project initialized with:

algokit init --template tealscript

boxes.algo.ts:

import { Contract } from '@algorandfoundation/tealscript';

// eslint-disable-next-line no-unused-vars
class TestContract extends Contract {
  items = BoxMap<bytes, bytes>();

  notOkay(): void {
    const item = this.items('test');
    if (!item.exists) {
      item.create(128);
    }
  }

  allOkay(): void {
    if (!this.items('test').exists) {
      this.items('test').create(128);
    }
  }
}

> tealscript boxes.algo.ts

The code produced for notOkay is (all commented out):

// /*
// notOkay(): void {
// const item = this.items('test');
// if (!item.exists) {
// item.create(128);
// }
// }

I'm guessing the syntax isn't supported but there's no information about it in the IDE (VS Code) / the tealscript cmd.

Huh interesting. This (saving a reference to a storage property in a variable) definitely isn't supported yet but I would have thought that it would throw an error.

Short term I'll get it to throw an error message, long term I'll work on supporting this because I imagine it's not uncommon to want to do this.

The actual issue here is no feedback from the tealscript boxes.algo.ts call. I thought it has produced the teal file above (with the commented out code) but it didn't and it was just some old code.

The tealscript boxes.algo.ts boxes.teal still provides some error information:

@algorandfoundation\tealscript\node_modules\typescript\lib\typescript.js:29399
        return node.kind === 208 /* SyntaxKind.PropertyAccessExpression */;
                    ^

TypeError: Cannot read properties of undefined (reading 'kind')
TEALScript can not process CallExpression at .\contracts\boxes.algo.ts:7:16
    .\contracts\boxes.algo.ts:8: this.items('test')

Ahh ok yeah that makes sense. Yeah definitely need to add a proper error message for that.
