Do you maybe have a file /tmp/.interfaces.apply which has invalid/bad content?

If so, try removing that file and then making changes again.

Or maybe whatever is holding /tmp is full (RAM disk? dataset? disk?)

[liug2]

Thanks for the reply!
The file you mentioned is only 0 byte and the /tmp is only 11% usage.

The php error seems to say the function expects the first argument to be type array, but the boolean false was passed instead, triggering the TypeError.

The false part should be an array read from that file (or an empty array if the file doesn't exist) so the file being there and empty/corrupt meant it ended up false instead of having a proper value.

Not sure how it ended up that way though, I can't replicate that here.

[liug2]

Thanks for the hint!

After I deleted that empty file /tmp/.interfaces.apply, I can edit interfaces now. The issue is resolved !

Based on the timestamp, that file seems to be there since May 10, 2023. It's a mystery to me. I guess since nobody from my team tried to edit interfaces since then, so no one encountered the error.

Interesting that it's been around that long and hadn't been removed/cleaned up.

The code should absolutely handle that situation better, though. I opened https://redmine.pfsense.org/issues/15423 so we can address that for the next release.
