LGTM, I'll fix the integration tests unless you want to take a stab at it (looks like an issue with Laravel).

[hendrikheil]

Sure thing, I'll take a look

[hendrikheil]

Seemed to be an issue with the locked version of laravel/sail's 8.0 runtime. Simply getting a new lock file should do the trick 🤞

@CiiDyR is this PR ready to be merged?

[hendrikheil]

Yep, should be good to go, same with #127

[withinboredom]

Thanks @CiiDyR! I have no idea what the DCO action is or why it is failing. I think I have to do something special, but I have no idea what nor do I currently have access to any chat channels to ask silly questions. I'll make a point to figure it out this week. But yeah, this can be merged as soon as I figure out this mysterious action that I didn't add to the repo means.

[hendrikheil]

I think I fixed it by amending the commits like described here: https://github.com/src-d/guide/blob/master/developer-community/fix-DCO.md

So should be ready for merging now, I guess at least...

[withinboredom]

Awesome! I'll get this merged this evening!

[withinboredom]

@CiiDyR, I've updated some bits, would you mind rebasing on the latest main? The composer.lock conflict is your earlier PR's changes.

[hendrikheil]

For some reason the rebase duplicated the commits, so in order to keep the history clean, I just made new commits.
Not sure what tests are failing now, but it looks unrelated to the CloudEvent changes (at least to my untrained eyes) :)

[hendrikheil]

@withinboredom As far as I can tell the jobs fail because update-examples.php doesn't set the remote origin to the source repo. So composer looks for feature/cloudevent-replacement on dapr/php-sdk, which doesn't exist.
As far as I can tell the best way to solve this would either be to add logic to add the repo to the composer repositories key.
So I've just gone ahead and added something that should resolve the issues.

[withinboredom]

Thanks @CiiDyR! Sorry for the delay, my computer died a horrible death after 4 years of fantastic service. I've just got my new computer all set up and I'll be getting to this sometime in the next week.

Thanks again for your contribution here!

[hendrikheil]

Any updates on this PR? :)

[withinboredom]

Sorry @CiiDyR, I'll get to this soon!

[withinboredom]

In exactly 2 weeks, I'll be going on a sabbatical from regular work for 3 months. Until then, things are just too crazy to get this merged. Once I'm on my sabbatical, I plan to focus on this and a couple of other open-source projects.

I just wanted to give you a heads up @CiiDyR. I haven't forgotten about you or this PR.
