template-parser may also need to be updated to export meta property for the parser. We had to do this as a workaround to get template linting working with flat configs:

const angulareslint = require("@angular-eslint/template-parser");
...
{
	// WORKAROUND Fix for missing meta property on the template-parser.
	files: ["**/*.html"],
	languageOptions: {
		parser: {
			meta: {
				name: "@angular-eslint/template-parser",
				version: "17.3.0",
			},
			...angulareslint,
		},
	},
},

Without this fix, you receive the following error: Could not serialize parser object (missing 'meta' object)

@JamesHenry As I can see, you have closed the pull request that fixed the issue. Will this be resolved soon?

@moh4sa It is dependent on typescript-eslint/typescript-eslint#8211

Most likely ESLint 9 support will land via typescript-eslint v8 in angular-eslint v18
