ESLint identifies type error in generated code for tests

[BurtHarris]

I'm working on integrating ESLint into antlr4ts. One error keeps coming up that seems to be a real bug, apparently in generated test code. The message is: Argument of type 'Token' is not assignable to parameter of type 'number'.

It repeatedly appears on the process.stdout.write line below, objecting to _localctx._a._start being used as if it is a number.

public s(): SContext {
	let _localctx: SContext = new SContext(this._ctx, this.state);
	this.enterRule(_localctx, 0, MParser.RULE_s);
	try {
		this.enterOuterAlt(_localctx, 1);
			{
			this.state = 4;
			_localctx._a = this.a();
			process.stdout.write(String((_localctx._a != null ? this._input.getTextFromRange(_localctx._a._start, _localctx._a._stop) : undefined)));
			}
		}
		catch (re) {
			...

Problem was a misdeclaration of getTextFromRange.
