I see this issue on Minecraft 1.14.2-pre2. My server is a VPS with openjdk version 1.8.0_171. My client is using render distance 20. I have been unable to find an exact method which reliably produces the bug, but here is what I know:
EDIT: The bug always seems to affect the same chunks.
Connecting and disconnecting enough times will cause the bug to occur. No other player actions are necessary. The bug appears to be especially likely to occur if you disconnect, wait for the chunk to unload, and then reconnect.
Running the "--forceUpgrade --eraseCache" will fix the problem temporarily, but it will be back.
We have a large world: 2.3 GB. I have attempted to downsize it by keeping only the .mca files which contain buggy chunks. As far as I can tell, the bug does not occur on the downsized world.
Mapcrafter's "nightlight" render mode shows dark chunks all over the place, including places where the bug occurs. See screenshot.
Mapcrafter has not yet been updated for full 1.14 compatibility, so I am not sure what this indicates.
It is not necessary to run mapcrafter in order for the bug to occur

I have attached two versions of an .mca file which contains buggy chunks. One version contains the lighting bug, and the other does not. Some block coordinates within an affected chunk are X=96, Z=3108.
