Redis "Waiting for other jobs to finish" but there are no other jobs.

[richpav]

I have audiogram installed on a fresh Ubuntu Bionic Beaver VM. Installed exactly according to instructions. Started afresh twice already. Node version v8.10.0. Using Redis because I was getting errors like this:

info: Listening on 8888
SyntaxError: Unexpected end of JSON input
    at JSON.parse (<anonymous>)
    at load (/home/vagrant/audiogram/lib/transports/redis/fake.js:14:15)

    at Route.dispatch (/home/vagrant/audiogram/node_modules/express/lib/router/route.js:112:3)

My settings/index.js has this:

module.exports = {
  workingDirectory: "/tmp/",
  storagePath: "/home/vagrant/audiogram/file-storage/",
  redisHost: "127.0.0.1",
  worker: true
};

When I try to render the page displays "Waiting for other jobs to finish, #1 in queue" but nothing happens. Deleting the Redis cache with redis-cli flushall doesn't help.

I see this error was addressed a year or two ago, but I don't see a solution that works with Ubuntu.

I have gotten this to work once or twice, but now I can't even get it to render 60 seconds of audio with Redis off.

It looks like that the queue is stored in a file called ".jobs" at the root. Here is how it looks like:

So if you don't care about its unfinished tasks, just delete the file. It will automatically create a new one.
