I think somehow you run the script against the transform file.
The original file at line 288, it's .map() not .mapAsync()
https://github.com/minhna/meteor-async-migration/blob/main/transform.ts#L288

@minhna I think that I know the problem.
My codebase does not declare a new collection using new Mongo.Collection('collection'). I need to add a case to validate it.

meteor-async-migration/utils.ts

Lines 507 to 531 in 24da9a1

	case "NewExpression": {
	if (p6.value.init.callee.type === "MemberExpression") {
	const { object, property } = p6.value.init.callee;
	if (
	object.type === "Identifier" &&
	object.name === "Mongo" &&
	property.type === "Identifier" &&
	property.name === "Collection"
	) {
	result = true;
	}
	}
	break;
	}
	case "MemberExpression": {
	const { object, property } = p6.value.init;
	if (
	object.type === "Identifier" &&
	object.name === "Meteor" &&
	property.type === "Identifier" &&
	property.name === "users"
	) {
	result = true;
	}
	}

Yes, you can modify it to make it works with your code base.
