Cannot create a trigger (/subscriber) for an platform event

[Theodoor van Donge]

Reproducible by following the steps:

1. Create a new trigger
2. The menu opens where you can select the SObject type.
3. Since there are now platform events, you can also create a trigger on a platform event, that works like it is a subscriber on that event. But you cannot select the platform event type in that select field.

Interesting. I thought I'd added full support for platform events as a variant of SObject, but guess I might have missed this aspect. I'll take a look. Thanks for reporting!

[Theodoor van Donge]

Well the issue is solved by adding the platform event to the package.xml file and retrieving it first.

[Scott Wells]

Hmmmm...that's odd. It should be using the SObjects in the OST to build the list of SObjects for creating a trigger. Did you happen to regenerate your OST in between as well? or perhaps save that .object file which would regenerate just that portion of the OST?

[Theodoor van Donge]

Yes you are right, i also needed to rebuild the OST. (only the SObject part, so it was quite fast)
