Android WorkManager chained work not running on alpha04

[UPDATE] this has been solved in alpha09

I´ve two works that gets chained by the WorkManager alpha04 beginWith and then api´s.

fun updateData() {
   createWorkRequests()
   runDataDownloadWork()
}

private fun createWorkRequests() {
    dwElementsWork = OneTimeWorkRequestBuilder<DWElementsWork>()
            .addTag(TAG_ELEMENTS_WORK)
            .build()
    dwElementTypesWork = OneTimeWorkRequestBuilder<DWElementTypesWork>()
            .addTag(TAG_ELEMENTS_TYPE_WORK)
            .build()
}

private fun runDataDownloadWorkNoStatus() {
    WorkManager.getInstance()!!
            .beginWith(dwElementTypesWork)
            .then(dwElementsWork)
            .enqueue()
}

They get called on my MainActivity.kt file and somethimes just the first one gets executed dwElementTypesWork some other times both, and just in a few cases none of them. Am I missing some configuration? The documentation is pretty straight forward.

This is the logcat output based on the WorkManager log:

Sometimes it throws the following errors for the second job:

E/WorkerWrapper: Status for cfaeae5c-fafd-4b9f-a77b-909625bdb26b is BLOCKED; not doing any work

Would add a comment, but can't comment yet on answers. The above answer by Budius works as a "fix". We had the issue with the last Worker for the chained work never being started, and it stayed forever on ENQUEUED. Setting a delay on the "ending" worker solved it.

I had the same issue (I've found your question searching for it).

It seems that it's broken on Google side and they should fix it. I'll try to fire a bug report later on.

For now I've "fixed" it by delaying the work by 1 second. Like following:

OneTimeWorkRequest.Builder(MyWorker::class.java)
// TODO whenever WorkManager is updated, test this again
// it was not working without the delay https://stackoverflow.com/questions/51078090/workmanager-chained-work-not-running#
.setInitialDelay(1, TimeUnit.SECONDS)

I know it's a bad hack, but for now it works.
