Will this be merged at some point? I'm running into the same 3.14 issues

[StuffbyYuki]

@mpreusse Looking at this this week

[StuffbyYuki]

@AvinashYerra Can you add DCO checks on your commits?

[AvinashYerra]

Hey @StuffbyYuki, this is my first time doing the DCO thing. Please lmk if you want me to change anything

[StuffbyYuki]

@AvinashYerra I ran the ci workfkows again but it looks like it failed. Here's some guidance on DCO checks!

Use git commit -s to add the sign-off automatically:

• git commit -s -m "Your commit message"'

To fix a commit that is missing the sign-off:

• git commit --amend -s

To add a sign-off to multiple commits:

• git rebase HEAD~N --signoff
