Chart looks only grey, does not show the color - Chartjs,discordjs

Question

I was designing a discord.js code that will show message and voice stats of a member which may lead to prizes according to leaderboard of it.

Normally, my graphs somehow should have been looking something like these graphs:

(the graphs shown above are respectively voice and message stats of a discord server)

But when I enter commands, it shows these colorless graphs: (it is not about its design but its colors)

Between those two graphs, there are no code differences, no node.js version changes, no platform changes or such.

I have been working on this project for a long time but after one month or so, I still could not find any error on my codes. Maybe I missed something. Can someone help me on this please? Thanks.

The color you're getting now is the default color the library has set rgba(0, 0, 0, 0.1), and this is because you're giving an array instead of a string or a canvas pattern/gradient object borderColor: [].concat(dataColors). General stats command line 97
