How to compile from pug files that uses pug locals?

[7iomka]

[easygettext] could not read: './dev/pages/base-variables.pug' using acorn as parser
Trace: TypeError: ./dev/pages/base-variables.pug:13
    11| - let langInUrl = false
    12| - let appLinkIconSuffix = ''

    14|         let languages = Object.keys(isoLanguages).filter(code => {
    15|                 return _.includes(supportedLanguages, code);
    16|         }).map(code => {

Cannot read property 'includes' of undefined
    at eval (eval at wrap (/Users/7iomka/Desktop/Projects/Core_new/core_new/node_modules/pug/node_modules/pug-runtime/wrap.js:6:10), <anonymous>:752:11)

My locals and pug build looks like this

const _ = require('lodash');
const locals = { _, ... }
...

 // Compile the source code of file with compilation option from pug-config
      const compiledFunction = pug.compileFile(source, options);
      // Render a set of data
      const html = compiledFunction({
        ...locals,
        langToRender: lang,
        variablesToRender: locals.includeVariables(lang),
      });

How I see you pass your own locals (2nd parameter), and user defined is skipped.
Need somehow to make possible to extend it with user-defined.

	templateData = pug.render(data, {
	filename: filename,
	pretty: true,
	require: () => {
	},
