What is the problem?
Attempting to submit a block on https://en.wikipedia.beta.wmflabs.org/wiki/Special:Block I get:
PHP fatal error: Argument 3 passed to EventFactory::createUserBlockChangeEvent() must be an instance of Block, null given
Does not happen on test or my local VM (which is the same version of core as beta).
Right now beta is MediaWiki 1.33.0-alpha (b0a3dd3) 16:36, 31 March 2019.
Someone may also want to check the appropriate logs for around 18:30-18:40 31st March UTC, which is when I was having this issue.
Steps to reproduce problem
- Submit any sort of block against any user
Operating system: Debian 8 GNU/Linux
Browser: Firefox 60
