ast.params.map is not a function error

[meirish]

Moved from ember-template-lint/ember-template-lint#2027 - I was seeing an error when attempting to fix the no-model-argument-in-route-templates.

Should this statement be guarded in a ast.params.length check?
https://github.com/ember-template-lint/ember-template-recast/blob/v5.0.3/src/parse-result.ts#L346

The ast used on line 346 can be of one of the following types:

ember-template-recast/src/parse-result.ts

Lines 274 to 278 in ec7c070

	ast:
	| AST.MustacheStatement
	| AST.SubExpression
	| AST.ElementModifierStatement
	| AST.BlockStatement,

Each of these types of node have a params property. It means that ast.params is never supposed to be something else than an array.

Have you been able to isolate the template causing the ast.params.map is not a function error error? If yes do you mind sharing it?
