I can confirm this behaviour. We imported all topics into “uncategorized” and are now gradually recategorizing them. I just bumped into that 422 error. After reading this topic, I changed the title to make it comply with the minimum length and it worked. But it would obviously be nicer to have a meaningful error message, even if it just pointed into a general direction like “Topic failed validation. Does the title meet requirements?”. Even better would be to not produce an error at all and continue to allow non-compliant topic titles even when they are moved.
