I don't have the exact download link for the version I am on, but use the Forge version of Dynmap.
The closest I could get the Bukket version was have it load without errors, but then render nothing.
A link for a version that should work is:

The forge version works great, just have to be careful of it getting flooded with pocket dimensions.
