Liquid in Lightning Port Detection Alert (False)

If your iPhone or Lightning accessory is wet

Unplug all cables or accessories. Don't plug them in again until they're completely dry. ... If you see the alert again, there is still liquid in the Lightning port or under the pins of your Lightning cable. Leave your iPhone in a dry area with some airflow for up to a day.

Same question. Have had my iphone 12 1 week, and all of a sudden getting this error (and no longer have any charge). The phone has been no where near water. Just traded in my 7S - never had issues with it. How do I fix this?

I have have received the same message multiple times on my iPhone XS Max. After conducting some research online, I found that this is a very common issue for lots of people after updating to iOS 14. It is actually nothing wrong with the port (usually), but a software glitch that came with iOS 14. The only thing to do now is wait for Apple to release a software update to fix it.
