On a fresh project with ash_authentication installed, an insert into the user table triggers a rollback. However, it works fine for other simple resources.

Are there any log messages showing warnings for unhandled errors?
zachdaniel
Definitely something strange.
zachdaniel
I will have to look in a few days. Does the error go away if you don’t use ash_events?
albin
yes, without ash_events, adding a user via /register or via ash_admin works as expected
zachdaniel
Interesting. Perhaps @Torkan will have a chance to look into this? Otherwise, I will look at the repro in a few days.
albin
nothing I could find in the logs. Here’s the full log:

OK, when I clicked create on User resource in Ash Admin, the page froze for about 5-10 seconds and then gave me this error:
zachdaniel
froze for 5-10 seconds
wacky. That sounds like some kind of ash_admin error handling bug?
But this appears to be something we essentially just didn’t consider which is that ash_authentication depends on the name of the action lining up to do what it does.
I think we need to make two changes:
contextfrom the parent to the childchange set_context(%{strategy_name: :password})so that ash_authentication picks it up from the contextAshEvents is pretty young, so there may be interactions like this that need to be considered.
#1 is relatively straightforward to do if you’d like to try your hand at a PR. In the action wrappers:

Here’s a draft PR I created. Please review.

LGTM, will let @Torkan review. It is a draft, would you prefer it not be merged? Does that PR resolve your issue?
