The typing of chart.js is NOT our friend and it shows again. Expecially the type ChartOptions that applies a deepPartial on each of its properties, including the plugin recently introduced: chartShowValuesPlugin.

Long story short, if provided with showValues=true, the plugin REQUIRES a callback function to format the data value. Unfortunately, the DeepPartial completely hides this requirement.

This bug was also missed because we do not directly test chart.js lib in our tests and it will be the subject of a task in the near future. In the meantime, we will strengthen the test case in our main integration (Odoo).
