Could not render map using renderer net.craftcitizen.imagemaps.ImageMapRenderer #27

Closed skeddles closed 3 years ago

The plugin worked fine at first, I downloaded and placed like 5 maps, one's 2x3, and they worked between restarts. Then one restart they randomly stopped working. The maps were blank, and it's spamming the below error in my server console:

I can still download maps, but when i place them the item frames are blank.

I am using minecraft 1.16.5, with a paper server (paper-1.16.5-526).

It seems like Java is unable to find or initialize a graphics environment on your server.

You might have luck running the server with the -Djava.awt.headless=true Java parameter, alternatively you might have to check your server configuration so Java can find the graphics environment—it's not something I can influence with the plugin, sadly.

Also see #15, which is probably a related/similar issue. (-> unset DISPLAY might work as well)
