Thanks, @Alt-Shivam.

Check Yaml...............................................................Passed

Based on your previous comment, isn't it a bit surprising that there are no errors?

[Alt-Shivam]

Yes, @joshmoore Basically I used a different YAML checker in this case.
and this is slightly less strict and only checks the validity.

but in the previous case, the YAML linter is kind of strict one which checks line lengths, brackets, extra spaces and extra symbols in YAML

[Alt-Shivam]

I don't want to make lots of changes in the codebase, so I chose this one.
but If you like the strict one, Then I can also accommodate that one :)

Ah, fair enough. Let's keep https://github.com/adrienverge/yamllint.git on the long-term list, but 👍 for starting with the easier introductions.
