Building php files in Gulp --- TypeError: Cannot read property 'php' of undefined?

Question

PHP

TypeError: Cannot read property 'php' of undefined
This error is displayed in the console when trying to build php files from one folder to another.
No actions are taken on the files, a normal ejection.
Path to files:

const path = {
    src: {
        _lcss:   'src/libs/*.css',
        _ljs:    'src/libs/*.js',
        js:      'src/js/*.js',
        phpsc:   'src/php/*.php',
        scss:    'src/sass/style.scss',
        img:     'src/img/*.*',
        svg:     'src/svg/*.svg',
        fonts:   'src/fonts/**/*.*',
        deploy:  'dist/**/*'
    },

    dist: {
        css:     'dist/css/',
        js:      'dist/js/',
        phpsc:   'dist/',
        img:     'dist/images/',
        fonts:   'dist/fonts/',
        scss:    'dist/'
    },

    watch: {
        js:      'src/js/*.js',
        phpsc:   'src/php/*.php',
        scss:    'src/sass/style.scss'
    },

    clear: 'dist'
};

Uploading php files:

gulp.task('php:build', () => {
    return gulp.src(path.src.phpsc)
        .pipe(gulp.dest(path.dest.phpsc))
});

Console error log:

Closing question, syntax error =\

Answer 2

What does php have to do with it is not clear, but the error is somewhere in the script, which says that they are trying to look at a variable with a field named "php". And this variable has the value undefined (i.e., the value is not defined)
