Bot not working

[mbanon]

I added the Stale bot to some of my repos a couple of weeks ago, but it didn't to anything to the open issues. I've changed the yaml file a few times to see if it makes the bot work, but no luck. This is the current stale.yml file (in the .github folder of the master branch of each repo I'd like the bot to work in):

# Configuration for probot-stale - https://github.com/probot/stale

# Number of days of inactivity before an Issue or Pull Request becomes stale
daysUntilStale: 15

# Number of days of inactivity before an Issue or Pull Request with the stale label is closed.
# Set to false to disable. If disabled, issues still need to be closed manually, but will remain marked as stale.
daysUntilClose: 7

# Only issues or pull requests with all of these labels are check if stale. Defaults to `[]` (disabled)
onlyLabels: []

# Issues or Pull Requests with these labels will never be considered stale. Set to `[]` to disable
exemptLabels:
  - pinned
  - security
#  - "[Status] Maybe Later"
  - pending

# Set to true to ignore issues in a project (defaults to false)
exemptProjects: false

# Set to true to ignore issues in a milestone (defaults to false)
exemptMilestones: false

# Set to true to ignore issues with an assignee (defaults to false)
exemptAssignees: false

# Label to use when marking as stale
staleLabel: staledByBot

# Comment to post when marking as stale. Set to `false` to disable

Any clues on what's going wrong? Thanks!

@mbanon you got an invalid yaml file, remove the indentation for only: issue and try again.

@AdmiringWorm Ok I'm trying now. It's confusing because YAML validators stated that the file was correct. How long may take the bot to fire for the first time?

[AdmiringWorm]

Well, according to the one I use, it says invalid (https://yamlvalidator.com/)

I'm not completely sure how long it takes before the bot fires. According to the docs, it may take over 24 hours after the initial setup, but I believe when I fixed a mistake in my own yaml file, it started after a few hours (didn't notice the mistake until after a few days though).

Funny, because this one said it was correct https://codebeautify.org/yaml-validator !

The bot just fired now, so THANKS! It worked :)
