Gulp Build Issue with Inject

I recently installed blur-admin but I am having difficulties initiating the app via the _gulp serve_ command. The problem seems to relate to the inject task that runs after the 'html' task in **build.js**. Below is the error that I keep getting:

$ gulp serve
assert.js:42
throw new errors.AssertionError({
^

AssertionError [ERR_ASSERTION]: Task function must be specified

I have tried updating the code with the latest syntax but this results in a different issue related to the 'inject' task definition. Here is the rewritten segment of the code:

`gulp.task('html', gulp.series(['inject', 'partials']), function a ()`

Here is the corresponding error message:
$ gulp serve
assert.js:42
throw new errors.AssertionError({
^

I am wondering whether this is an issue with any of my package versions or with the task definitions.
