Error messages appear during the installation but the adapter seems to run fine

If you receive error messages similar to the following the optional dependency "canvas" is not installed. The adapter works fine without canvas but for the full functional range (e.g. "map.deebotPositionCurrentSpotAreaID") you must install canvas.

Node.js upgrade

Error: The module '/opt/iobroker/node_modules/canvas/build/Release/canvas.node' was compiled against a different Node.js

cd /opt/iobroker/node_modules
npm rebuild canvas --update-binary

If the error still persists:

cd
sudo npm uninstall canvas
cd /opt/iobroker/node_modules
npm uninstall canvas
npm install canvas

Model specific issues

It's very likely that this is a firmware bug. You can use the corresponding option in the adapter config as a workaround.
