[ngbot]

I see that you just added the PR action: merge label, but the following checks are still failing:
     missing required label: "PR target: *"
     status "ci/circleci: lint" is failing
     status "code-review/pullapprove" is pending

If you want your PR to be merged, it has to pass all the CI checks.

If you can't get the PR to a green state due to flakes or broken master, please try rebasing to master and/or restarting the CI job. If that fails and you believe that the issue is not due to your change, please contact the caretaker and ask for help.

@lordrip Could you please fix you commit message: docs(http): fix a typo in code comment. Thanks.

[lordrip]

@vicb Yes, done, where can I find some guidellines for the ci/cicleci? just to make sure that I'm passing al the CI test (for example, to avoid this status "ci/circleci: lint" is failing), thanks a lot for all the people who makes Angular!

[vicb]

@lordrip thanks !

The easiest to pass the circle ci test is to format your code before submitting a PR by using
gulp format

For now formatting the code takes too long but we have a better system in the pipe that will format only the lines touched by your PR. Stay tuned.
